► According to an article in The New York Times, information given by the surviving suspect in the Boston bombings, Dzhokhar Tsarnaev, indicates that the brothers worked alone and were not connected to a larger terrorist organization. Investigators say that the older brother, Tamerlan, was radicalized via the Internet. The two had been planning the attack since at least February 6, when the brothers purchased fireworks in New Hampshire. The explosives in the fireworks were used to make the two pressure cooker bombs.
► Charges have been dropped against Paul Kevin Curtis, the Mississippi man who was arrested on suspicion of sending letters containing ricin to Senator Roger Wicker (R-MS) and to President Obama. Curtis, a vocal conspiracy theorist, has been arrested four times since 2000 on various charges, including cyber-harassment. Late yesterday, according to The Washington Post, investigators in hazmat gear searched the house of another man, Everett Dutshke. Both men maintain their innocence.
► A report by the Congressional Research Service indicates that while the European Union (EU) and the United States have coordinated on counterterrorism efforts since 9-11, challenges persist in issues such as privacy and data protection. According to the report: “The EU considers the privacy of personal data a basic right and EU rules and regulations strive to keep personal data out of the hands of law enforcement as much as possible.” This viewpoint has hampered agreement between the EU and the United States on issues such as tracking terrorist financial data and sharing airline passenger information.
