NYC prohibits unlocked paint, markers for under-21

"The law, authored by City Councilmember Peter F. Vallone Jr., outlaws the possession of graffiti instruments in public places by people under the age 21. Under the new bill, it will be a criminal violation to carry spray paint, broad-tipped markers or etching acid unless it is enclosed in a locked container, or if the tools are needed for educational or professional purposes."
