Re: Help needed with graffiti
+ 1 "swag"
+1 take a picture, then report it.
my city has a "gang unit" and a unit specificlly for tagging. All my cases or arrests involving tagging get picture documented, mapped (you can print a google map with a marker) and emailed to that unit. When a kid is busted in that district his tags get matched , any other get added on his charges.
Even regular citizens can call and get that email down here, then just email them yourself.
Relevant info to include is :time left to time discovered, date, method or chemical used to apply (scratches, ink, shoe polish, paint, marker), location, color or pigment used , finger prints at stops or points, size of overall tagg, estimated damage cost
