Legal Question in Criminal Law in California

It sounds pretty unlikely you would be prosecuted ... although I suppose it is theoretically possible depending on facts and injuries. I would talk face-to-face with some local criminal defense attorneys to put your mind more at ease. Good luck!

When confronting an intruder in your home you are allowed to use as much force as is reasonable under the circumstances. You will likely get the benefit of the doubt if the reasonableness of your actions isn't clear. But I can think of scenarios where the acts you describe would not be reasonable -- for example, if the intruder surrenders, turns to flee, etc.
