[Chief Todd] Stovall told the group of almost 40 residents that beginning in 2013, the department would deploy a new street crimes unit to high crime areas on foot to take back the streets.
“[Police are] going to be in SWAT gear and have AR-15s around their neck,” Stovall said. “If you’re out walking, we’re going to stop you, ask why you’re out walking, check for your ID.”

“To ask you for your ID, I have to have a reason,” he said. “Well, I’ve got statistical reasons that say I’ve got a lot of crime right now, which gives me probable cause to ask what you’re doing out. Then when I add that people are scared…then that gives us even more [reason] to ask why are you here and what are you doing in this area.”
The Reason’s Hit & Run Blog has this article on random ID checks. Apparently, according to the article, this is not completely new and that a few other cites have been doing this type of thing for a while now.
