"Maybe giving the police Tasers is a bad thing, but I think the alternative is that the police would routinely carry guns ..."
1) Tasers aren't effective against guns because guns have a longer range than tasers. This is one reason why you don't fight snipers with tasers.
2) Policemen have traditionally had recourse to a whopping-great stick aka a truncheon. What's the problem with using this instead of a tazer?
3) I don't know how old you are, but if you're about my age you'll clearly remember policemen using long-range devices known as "plastic bullets" in Ireland during the Troubles. AFAIK these devices are still in the police armoury.
4) "These feral children" ... thanks for taking the time out of your day to stop reading the Daily Bile and type its views into your web-browser. I wonder: do you even know what the word 'feral' means? If you do, why not use one of its synonyms instead of just repeating the same phrase everyone else uses - it would show at least _some_ independence of thought outside the BileBrain.
"...there are some kids roaming our towns who will only respond to threatened, or actual, violence."
There are some adults like this as well, and its amazing how many ordinary people act this way when approached by some shouty-arse nob in a uniform who hasn't got the slightest intention of explaining his actions to them, despite being a public _servant_.
If had a servant who acted that way I'd sack him.
