Since 9/11, we've been constantly warned that another terror attack on the U.S. is inevitable. But there haven't been any bombs. Why? Some of it is due to improved surveillance, security, and information-sharing, you've got to assume. Some of its is because there are so many other places to wage jihad – like Iraq and Afghanistan. But another big reason why there hasn't been another strike on America may be that terrorists hate to commute to work.

"Most terrorists live close to their selected targets," a new National Institute of Justice report finds. "According to our analysis, almost half (44 percent) of all terrorists examined lived within 30 miles of their targets."

And that's good news for local law enforcement. Not only are the militants in the neighborhood. But they spend time in the area, ramping up for the big attack. Which gives cops a chance to catch 'em, notes the report, spotted by Drew Conway.
