From Bozeman Police: 

Since last fall, similar graffiti like in this photo has been found all over our community. Graffiti is very expensive to remove from brick or concrete walls and in many cases, depending on the age of the wall, can never be fully removed. The more graffiti in a neighborhood, the louder the message is sent that nobody cares. This in turn can set off a harmful cycle that encourages further crime in affected neighborhoods and business districts.

 If you have information about this graffiti or other illegally placed graffiti on buildings in our community, please call the BPD immediately at 582-2000. You may even be eligible for a cash reward!
