How to make the secret service nervous

[Ripsnort]

You know those little pen lites with the laser?  Bring one to a rally, turn it on, flash it a couple times, bet you can't run fast enough!

(I actually know someone that did this, a fellow I went to highschool with, no one has seen him since, I was just informed)

There have been a couple of occasions here in Columbus where people have done this to police officers and they have been arrested.  The charges end up getting dropped in court but most people now know that this prank is not worth a trip downtown.

That also works with soem military vehicles...
I heard some UN soldiers in Lebanon "flashed" some Merkava's with those. I heard merkava can turn its cannon quite fast

Haha Rip.

I live on a very busy corner, and some kids at a bus stop were flashing me and people on my big screen TV.  It was funny for the first minute - after that I considered flashing them back with the one on my Mossberg 590, but like it was previously mentioned, a ride downtown isn't much fun.
