I wrote on seeclickfix.com here before:

About 1/2 yr. ago when I was shopping at Home Depot/Emerville, when I checked out I saw 5 lines away from me; there is one non white cashier/female w/2 purchasers non white males, the 2 purchasers only bought spray painting about 6-7 bottle, the cashier showing from her smart phone to suggest ...what graph to use, -> I should took the picture at that moment.

About "graffic" Home Depot can help, they can trace who is the customer always buy spray painting -> trace their phone no., address give to Oakland Police Dept.; I reported once may be 1 yr. ago around 5-6 p.m. I saw all the graffic people together at one house at that time I had my husband in the car I can't be free to do anything, after I dropped my husband home I drove back there called Oakland Police Dept. gave the exactly the address around 7:30 p.m., -> Right now one building and related one related area already sealed by the board/all the windows and door. -> I think that building was foreclosure before and graffic people broken in and lived there and get together to have their meeting.

The City of Oakland Public Works Department has referred this issue to CODE ENFORCEMENT,. Please contact that department to follow-up (see "Other Helpful Links" at http://www2.oaklandnet.com/Government/o/PWA/Connect/ReportaProblem/index.htm#Links).
