They seem to show up in bunches.  But they can do a lot of damage.  Fortunately, some have bad luck, like this guy who pulled over a real cop.  If you aren’t a cop though, you could be in real trouble with people like this.  Now, 2 years ago (in November 2005) I wrote about what to do if you suspect you are being pulled over by a fake cop:  use your cell phone and dial “911” and ask the operator for help.  Be sure to stress that you are scared and have the operator either confirm that it’s a real cop following you or send the real cops asap.
