Here's a useful tip:
If you're being stupid and the cops cut you a break, it's probably best to avoid making the officers regret it by mocking their leniency on YouTube.
The following article that just moved on the Associated Press wire, if you stick with it to the end, shows what happens when you don't follow the above advice.
BC-US —Rocket Launcher-Hoax/150
Phoenix filmmaker jailed for rocket launcher hoax
PHOENIX (AP) — Phoenix police say they've arrested a man after he reportedly dressed a teenage relative in a sheet and sent him into a street to aim a fake rocket-propelled grenade launcher at passing cars.
Police spokesman officer James Holmes says 39-year-old Michael Turley was arrested Monday on charges of knowingly giving a false impression of a terrorist act, endangerment and contributing to the delinquency of a minor.
Holmes tells KTVK-TV (http://bit.ly/PmtGRg ) Turley filmed the teen pointing the fake grenade launcher at passing cars on July 28.
Responding police didn't make any arrests after Turley told them he was making a movie.
Police made the arrest after the self-described filmmaker reportedly posted a video on You Tube that said he was testing how fast Phoenix police responded to the mock terrorist.
