absolutely hate domestic violence and I feel more should be done to help protect women from it and help them to not feel scared to reach out for help.
The problem is.... sometimes domestic violence is not... it can be used (and from my experience an LEO IS used) as a tool of control by the "alleged" victim. I have seen people prosecuted for "crimes" that never occurred, and the "injuries" were self-inflicted.... but juries tend/trend to believe the side of the female regularly... and then totally disregard when/if the victim is male, as apparently males can't be victim(s) of it.
In once case, a spousal unit accused her husband of attacking her and scratching her arms. She had apparent bloody scratches on her arms... only thing, she forgot to clean under her fingernails, and the scratches would have been hard to do by a third party due to their directional swipes. There was still tissue there, whereas, the male had no tissue, and no fingernails to speak of that would have caused such injury. Due to the fact of how the law was written, he was still taken to jail and the DA prosecuted him. His saving grace was my testimony of the bloody tissue found under her fingernails and the lack thereof under his "nails", which were chewed to the nubs. Talked to two of the jurist in a conversation after the trial, and they admitted they were leaning towards a conviction until the tissue testimony was presented (and both of them were female).
Another case I know of (a friend and after I got out of law enforcement) involved a 16 year old daughter that had new (and illegal at her age) nose piercings, got into trouble, back talked her father when her boyfriend (8 years older) was present. The father went to spin the daughter around when she charged at him and her boyfriend hit him from behind, causing him to fall forward and the daughter fell onto a bed below him. He was holding himself off her and told the boyfriend that if he ever did that again he'd be picking teeth up from the floor. The daughter did not like that, bit the crap out of his upper arm and her new nose piercings scratched the inside of her nose as she was burying her face into the arm biting. The daughter called the Police, removed her nose piercings and then claimed that the father hit her in the face, causing her nose to bleed, showing a slight amount of blood she had wiped on her sleeve. Guess who went to jail and got a conviction?
I was VERY quick to arrest for family violence offenses.... but I realized that some of the violence was staged and would do as thorough an investigation as possible.
BTW, as far as I'm concerned, the "violence" can be mental as well as physical. Only thing is mental is not a criminal violation in most jurisdictions and can only be resolved by leaving the abusive partner.... which too many (both male and female) don't want to do, thinking for some reason that the actor can/will change.
