Baltimore does have money allocated to investigate graffiti and a division of officers who are tasked with documenting graffiti, writers who have been caught and locations. They are part of the Environmental Crimes Unit and have played a role in the arrests of individuals who have been caught. This isn't based on theory, opinion or speculation. Rather it comes from first hand experience and information obtained from people who have worked in the department, and writers who have been interrogated and questioned by the law. It is fact. There is nothing to prove, I'm merely stating this because some people don't realize this and it is useful to know. They use any tool available to gather information, including this site. This was stated by someone in the department. My point is that those who use this site should do like someone said earlier, watch what you say and post.
