When you think Farmington Hills , drug-relate executions don't leap to mind. "That is the reality. If you have a criminal organization that generates a lot of income, the heads of those organizations are going to live in nice neighborhoods, places they believe they'll be safe," said Wayne State law professor Peter Henning. "This type of killing is not generally a threat to the public, at least not at this point," Henning said. "It's not something you need to fear. The only concern is if it's a precursor to some kind of gang warfare. Then, you'd be concerned about third parties getting into the line of fire."
