►The National Hurricane Center predicts Hurricane Isaac will grow to a Category 2 hurricane as it passes over warm air in the Gulf of Mexico, follow the track of Hurricane Katrina, and make landfall near New Orleans on Tuesday. A Category 2 has winds between 96 and 100 mph and a strong storm surge. “Oil companies began evacuating workers and cutting production at Gulf offshore rigs in Isaac's projected path,” CBS News reports.
►DHS plans to use aerosol release of dead bacteria in the Boston subway to test new sensors developed to detect a biological attack. “After the subway stations close, S&T scientists will spray small quantities of killed Bacillus subtilis in the subway tunnels," Homeland Security News Wire reports. The bacteria is non-toxic for humans, animals, and plants. The sensors are the latest part of DHS’s Detect-to-Protect program. Earlier this year inert gases were released to track airflow in the subway to determine where to install the sensors.
►Suburban gun shops are the main source of guns used in crimes in the city of Chicago, according to a new study by the University of Chicago Crime Lab. “The study covers 17,230 guns the ATF successfully traced after they were recovered in Chicago,” reports the Chicago Tribune. However, many guns can’t be traced because of their age or “other factors.” The research also found that two gun stores were responsible for selling more than 10 percent of guns recovered by police. The second largest source was across state lines in Lake County, Indiana. “The numbers don’t mean gun stores are violating any rules, as guns are often stolen from their legal owners or bought legally by ‘straw purchasers’ who pass them to criminals who would be prohibited from buying firearms,” the Tribune reports.
