I wanted to update those that replied. My friend insisted on a trial, since he was innocent. No lie detector test was ever used. His lawyer recieved letters from both his ex and her son stating that there was no hitting and none was ever seen. Basically, they recanted their video taped statement. The Crwon stood up and explained to the judge on the day of the scheduled trial that their case "suddenly and unexpectedly evaporated". There were no charges (as yet) brought by the Crown against his ex.
So, in effect, this man lost months of time with his child, was embarassed, arrested, finger printed and jailed. For nothing. And nothing is happening to his ex for her lies.
Justice?
There is no justice when it comes to Domestics. If you are man and you have a woman who calls the cops you are in trouble. No matter what happened. No matter the truth. No matter nothing. You male= you in trouble. case closed.
Once charged, no matter how weak the case is it will be brought to trial and you lose time, money etc.
The bad news; Most peole plea since tehy want to see their children fast.
Good News: 50% of domestic trials are won.
