Public indecency? Dining and dashing?

Lock picking class would be cool

Try to start your crime by thinking differently where it helps.

No. Go big or go home!

Spit on the sidewalk
Illegally download music
Make a rolling stop at a stop sign
Share your Netflix account (with somebody not in your home)
Have anal sex in Alabama
Feed a homeless person in Philadelphia
Jaywalk
Ride a bike on the sidewalk
Mention assassinating the President
Remove the flow restrictor in your shower head
Get a happy ending at a massage parlor

no no no you go big or go home, like go straight to diamond heists and shit, you just do your research and organize and all (remember to use things like VPNs and burner phones!) , but somebody with no previous record of criminal activity will be the last person they suspect

Tax elision. (Not a crime but it's good for training purposes :-)
