In the first, a wife had to call in the police after her estranged husband turned up at her place to harass her. There was nothing to aid in his case, as he was loud, rude, very angry and seemed a little slow on the uptake (could be alcohol impairment). However, as loud as he was, he did do as the police officers said, as they had asked him: "do you want to walk away or spend the night in jail?" As he was walking away, the police arrested him, which i thought was a strange time to do so, since they had plenty of opportunity to do so earlier. Not sure why the change in mind, but it seemed like an odd time to do so (television program editing did not help). Funny thing the guy did was after he was arrested and cuffed, he started banging his head on the bonnet of the policecar, saying "why are you hitting me?"
The second incident was more disturbing for me. Basically a bunch of detectives in New Orleans left a bicycle in plain view, unlocked, on a street corner (in front of a church i think). The bike itself belonged to one of the detectives and looked pretty new. I had thought that entrapment was not allowed in the states. The amusing things that the detectives said when questioning the various suspects included "so who gave you permission to touch the bike?", which just reminded me of primary school mentality.
Still, watching the program reminded me of the various procedures that are required (on the part of the police) when trying to detain or arrest a suspect. =)
