Eddie, Though this sounds good and perfectly legal, i wouldn't advise it. When my beatin' happened, I went to complain for building up my case. What happen when I went into file a complaint was another story, as the officers behind the desk remarked to me "you sure you want to do this...remember, you live in the same city" and started laughing as if some sort of "set up" will be done if I did file.
Anyway...i'll just leave it up to Karma and let it be.
Sorry to hear that man.....but actually now a days officers are scared of I.A investigations. If they actually said that to you thats even more ammo to be used against them in a lawsuit. If you have a case of getting beat up and can prove it was excessive force then you have a great case. (Larry H. Parker?)
No officer can threaten you not to file a complaint.....if they do they better be ready to get to go pound sand, suspended or even fired. Now a days its a lot harder for Officers to get away with misconduct.....ever since Rodney King things have turned with legality wise against departments.
Remember this too, the city is liable for 95% damages if awarded to the person and the Officer is liable for 5% of that. So if there is a multi million dollar lawsuit and the city loses the officer will be paying 5% of that judgment. There has been Police departments that have been bankrupted because of this.
One of the many things they teach at the Police Academy's is liability against the department and your role as an Officer not to get the city and department into trouble.
Karma will get those bad apples....maybe they will come back as sloths when they are reborn.
