@hawkeye10,
He has said he won't sue but his case would be rather strong.
Is your porch a public place when it is clearly located on your property? Do you really think you can convince a jury of 12 citizens that it is a public place? If it is NOT a public place then the arrest was not valid under the statute.
That leaves the city with arguing
1. They didn't train the officer well enough in that he overreacted. (They lose)
2. The officer acted outside the law in his official capacity and the city is still responsible. (They lose)
3. The officer felt physically threatened and needed to end the confrontation but failed to put that in his report. (A hard one to argue considering the age of the officer and the person arrested. They probably still lose.)
Closing summation.
If you answer yes to these two questions then the arrest was not valid and you must award for the person arrested.
1. Was the porch private property?
2. Does the statute require it be public property for an arrest to be made.
