What is the problem being created? They were looking for a fugitive
Which is cool, as long as they don't get in the habit of "looking for fugitives" 24/7.
Why would they check everyone's ID instead of just the people who looked like the person they were looking for? At least people who are obviously the wrong age and sex...
Sure, and Eric Garner, Michael Brown were resisting arrest, and Freddy Gray was just being transported.
