Hankster,
I know what it says "you shall arrest if there is PC". It means that the officer " shall", make an arrest. It means he has no choice and that he better not, "not" make an arrest, because all the liability is on his shoulders, and the department and himself have immuntiy as long as he does make "an" arrest, (not the correct arrest or legal one just that you make one). So as an officer if you exercise discretion regarding investingating DV, you could be held civillaly and criminally liable, but if you make an arrest, (regardless if it's correct or not), you have immunity. SEE THE PROBLEM???? The government protects you for violating someones rights, but potentially punnishes you for protecting them.....
