Here is how this debate should go:
1. Did the cops do break the law trying to enforce it?
2. Did the cops illegally enter the home of the defendant?
3. Does the home owner have the right to defend his home against illegal entry?
Thats all there is to this argument. If the cops broke the law trying to enforce it, they were wrong. If the defendant illegally entered the home of the police, would they have the right to use force to stop him?
