Since you are a cop, the solution is simple -
Just carry your taser with you, a can of OC, and then when you see the guy again, pop him with the taser, mace him in the face, and then beat him
within an inch of his life with a PR24 or an asp baton.
Just be sure you get the cuffs on him
before you start stomping his head into the asphalt.
Then charge him with resisting arrest, criminal trespass, obstruction, or some such charge, along with possession of a controlled substance, which
would of course be the small baggie of methamphetamine you planted on him as he lay on the ground unconscious and bleeding.
Also allege that he is running a meth lab out of his residence, so that any assets he may have will be seized during the search, which will obviously
involve tearing his home apart, destroying his personal belongings, and charging each of his family members as accessory to conspiracy to manufacture
and distribute controlled substances.
Be sure to call the state Dept. of Family and Children's services in order to have his children taken into permanent foster custody and placed into
either an orphanage or a group home.
During the trial, be sure to present false and misleading evidence in order to ensure a conviction and definite prison time.
Problem solved, in a distinctly American law-enforcement kind of way!
