Police around the world use everything from sonic blasters to pepper spray to skunk bombs to plain-ol’
dung to control crowds. But sometimes, the protesters can turn the
tables, with tools of their own. Take this clash in Greece, where a
protester uses a laser pointer to show where a riot cop is.

UPDATE: As our commenters note, a laser like this can do more than just show where an officer is; it can stun that cop with an extremely bright flash of light.
