It wouldn’t take a lot of money to compile a team of veterans to take out gangsters. I suppose you could call them a “Ronin team”. They would be the equivalent of “death squads”, but as long as they were discreet, and only disposed of serious multiple felon gangsters, and didn’t do too many, too fast, or all in the same place, I don’t think they would create too much of a stir.
Ten years ago a crack commando unit was sent to prison by a military court for a crime they didn’t commit.
These men promptly escaped from a maximum security stockade to the Los Angeles underground.
Today, still wanted by the government, they survive as soldiers of fortune.
If you have a problem, if no one else can help, and if you can find them, maybe you can hire... The A-Team
