I've seen the TV shows (or at least I saw a few before I decided they had started to bore) and I had expected to form the opinion of how difficult it was for the police and how well they handled situations. In fact my feelings were somewhat different. In the ones I saw they seemed happy to enforce their authority to such an extent the simple act of swearing, for example, proved to be an excuse to make an arrest. Admitting not at the first occasion but so what ?
I'm sure there are still folk who get excessively distressed at hearing words defined as swearing, but IMO that is a problem they have with their reaction. If they can live with it then fine. But one would hope one does not have wilting wallflowers in the force; and so for the police, swearing should be just ignored, and this would result in a greater respect for them and what they do. To do otherwise is for them to fail on the public service part of their duty, since the individual swearing is a member of the public, and probably feels their swearing is appropriate to the situation.
No' the last thing we need is more draconian laws for the irrelevant. Why should someone be forced to feel or think as the State requires ? Feeling or showing contempt is a personal decison not something to be arrested for.
