The Main Street area will get a boost from efforts of local business owners. Some minor changes to the type of products sold will help reduce crime. If local corner markets stop selling just a few products or certain items in single quantities, the minor street crime will start to go down.
The key is vigilance. Keep an eye on what happens outside your business or residence and report crimes, all of them, no matter who is responsible. If all residents did this all over OTR, the drug trade and the theft rings would dry up in the neighborhood. The drug trade has in the past used intimidation of some residents, so standing up to them requires police to lead the way and patrol the area.
