I’VE TWO DOGS....THEY LET ME KNOW WHAT IS UP.
"I was just lost your honor and knocked on the door to ask directions when the crazy lady assaulted me!"
"Your honor, let's go to the recording..... here you can see Mr Innocent trying the door to the house.... here you can see him trying to kick in the door.... here you can see him pull out a crowbar.... here you can see me coming around the corner... here you see him swing at me... . "
Like I said, cameras are for afterwards.
