• Network-based tracking, an alternative to GPS

    With improvements in network-based tracking police and first responders now have a reliable alternative to GPS tracking when searching for suspects or responding to 9-1-1 emergencies; using signals from cell phone towers to triangulate a phone’s location, network-based tracking has steadily improved and in some regards surpassed GPS-tracking; unlike GPS-tracking, network-based solutions cannot be jammed by a user and law enforcement officers do not need to carry any additional equipment; with network-based tracking police can find an individual’s position within fifty meters using data from cell phone towers; despite improvements in network-based tracking, the system is not perfect and GPS still has many strengths

  • Taser's AXON wearable camera system provides police concrete evidence

    Police officers in several states are testing out wearable cameras to help increase transparency and provide clear evidence in officer conduct cases; Taser Corp. has developed the Axon Personal Camera System for police officers; the Axon system consists of a small camera, capable of recording at thirty frames per second, that is attached to an officer’s ear; initially developed in 2008, police departments are only beginning to adopt the technology to help minimize complaints over officer conduct; departments that have tested the system find it particularly helpful in providing concrete evidence

  • Deleted text messages hamper police

    The number of text messages grows exponentially; this year, people around the world will exchange five trillion messages; phone companies either no longer keep back up copies of text messages, or keep them for a very short period of time; police is worried that this policy will hobble future investigations

  • Improving safety in the presence of chemical hazards

    A new kind of sensor could warn emergency workers when carbon filters in the respirators they wear to avoid inhaling toxic fumes have become dangerously saturated; first responders protect themselves from such vapors, whose composition is often unknown, by breathing through a canister filled with activated charcoal — a gas mask; airborne toxins stick to the carbon in the filter, trapping the dangerous materials, and as the filters become saturated, chemicals will begin to pass through; the respirator can then do more harm than good by providing an illusion of safety

  • 247 on U.S. terror watch list bought guns, explosives in 2010

    There are eleven reasons why an individual may not be able to buy firearms or explosives in the United States — for example, being a convicted felon or an illegal immigrant; those on the U.S. terror watch list, however, are free to buy firearms and explosives; according to the FBI, in 2010 247 of them did — a similar number to that of 2009; some lawmakers want the attorney general to be able to prevent an individual on the watch list to buy a gun, but the counterargument is that the list is not always accurate, and that the attorney general is a political appointee; moreover, the list is secret, and letting people know they are on it may complicate the ability of law enforcement to track them and their associates

  • DHS IG criticizes FEMA's IT systems

    DHS Inspector General says that FEMA’s IT systems “do not support disaster response activities effectively”; the IG recommends that FEMA develop a comprehensive IT strategic plan with clearly defines goals and objectives to support program IT initiatives, and that FEMA establish an agency-wide IT budget planning process to include all FEMA program technology initiatives and requirements

  • Car-based IED attacks an emerging threat in Mexico

    Intelligence analysts worry that Mexican drug cartels will increasingly turn to deadly car bombs in the escalating drug wars; drug cartels have already assassinated several government officials using improvised explosive devices (IEDs) planted in cars; in Mexico IEDs are easy to construct due to easy access to powerful commercial explosives that are widely used in the country’s mining and petroleum industry; due to strict gun laws, it is actually cheaper and easier to obtain explosives than guns; to defend against this emerging threat the U.S. consulate in Monterrey erected concrete barriers

  • From 2,700-year old mummy to today's infants

    A Vermont radiologist with a passion for archeology thought it would be a good idea to use a CT scan to find the cause of death of a 2,700-year old mummy in a Vermont museum; the Vermont medical examiner thought the same technique could be used to determine the cause of death of infants who die under suspicious circumstances, and other medical examiners across the country agree

  • Virtual Imaging: versatile detection at low radiation dosage

    Virtual Imaging, a Canon U.S.A. Company, is offering its RadPRO SecurPASS, a full body security screening system that detects and recognizes a range of objects and materials in about eight seconds per person; it uses transmission imaging with an exceptionally low dose of X-rays to scan for dangerous or illegal substances such as liquid explosives, drugs, copper wires, plastic, etc.; its applications range from civil security, that is, airports, seaports, railways, bus stations, to border security, prison security, and high level security as necessitated by nuclear power plants, military premises, and embassies

  • Missouri pounded by rains and tornadoes, thousands evacuate

    This week heavy rain storms are raging across the mid-west and south forcing thousands of residents in Missouri to flee as swollen rivers threaten to flood their homes; in some areas emergency responders do not have many options and can do nothing but hope that the levees hold; the mid-west will not see any respite from the storms until Thursday as another major storm system is about to hit; officials are bracing for substantial flooding; the region is still struggling to recover from major storms that spawned tornadoes in six states killing forty-five people and damaging structures; Missouri has requested aid from the Federal Emergency Management Agency

  • Japanese app helps spread earthquake warning

    After the 9.0 magnitude earthquake and tsunami ravaged Japan, hundreds of thousands of people have signed up for a new emergency warning app for their iPhones; when an earthquake is predicted to hit, the iPhone app, called Yure Kuru, will send out an alert and let subscribers know when the quake is coming, where the epicenter is located, and how bad the shaking will be; the app was developed by Tokyo based RC Solution Co., which specializes in mass alert systems and spreading information in the event of an emergency; since the 11 March earthquake, the company’s subscribers have sky rocketed from 100,000 to more than 1.5 million

  • Japan quake reconstruction could take ten years

    Yesterday an advisory panel to the Japanese government announced that it could take a decade to rebuild Japan after the 11 March earthquake and tsunami wiped out much of north-eastern Japan; the council said that the first three years alone would be devoted to building roads and erecting temporary housing for the thousands of families that have been displaced; rebuilding towns could take another four years and a full recovery might take even longer; the damage from the recent quake was far greater than the large quake that struck Japan in 1995; Prime Minister Kan’s cabinet has approved almost $50 billion in spending for post-earthquake rebuilding

  • Indian explosives detection technology comes to U.S.

    A south Carolina-based company signs a memorandum of understanding with India’s Defense Research and Development Organization (DRDO) to enhance the DRDO-developed Explosives Detection Kit (EDK) so it meets standards that will allowed it to be used by the U.S. military and homeland security

  • U.S. Army picks Android

    Need artillery support? Android has an app for that; or will have, soon enough; while Apple scrambles, Google’s Android is picked as the operating system for the U.S. Army’s and Marine Corps’ smartphones; third-party developers will receive kits in July, with testing scheduled for October
