I compiled all the laws relevant to graffiti/bombing in DC

I figured its a good thing to know what you can and can't be held accountable for in DC, so I looked up all the laws that could be relevant to anyone bombing in the city, including: breaking and entering, "gangs" (which crews can fall under), helping minors to commit crimes, destruction of property and the possession of graffiti materials.

TL;DR: Breaking and entering (e.g. painting in an abandoned warehouse) can get you 2-15 years. Bombing with minors can get you between $1000 fine to 6 months. Being in a crew (depending on whether or not you are prosecuted for being in a crew) can get you fined up to $5000 or 5 years in prison or both. Racking can get you no more than $300 in fines and no more than 90 days in prison, it's not illegal until you conceal whatever you're stealing, or take it out the store. For destruction of property you can be fined between $250-$1000, and not imprisoned more than 180 days. You can also be forced to pay for the costs of removal. Also, if you're a minor, your parents can get charged/fined too. Possession of graffiti materials with intent to vandalize can get you fined between $100-$1000 and are defined as "means any aerosol can, bottle, spray device or other mechanism designed to dispense paint or a similar substance under pressure, indelible marker, paint stick, adhesive label, and engraving device capable of leaving a visible mark on a natural or man-made surface"

TL;DR of the TL;DR: don't get caught
