Ok, and then ten of your football hooligan buddies jump in. You are making a mistake in looking at it from a scenario based perspective - one can easily craft any scenario to fit their argument. Also, a ten cop dog pile could certainly kill someone.
> which country...
Any country in which overwhelming nonlethal police force is not unfailingly on hand everywhere... so every country. Consider it from the state's perspective: lose control of the population or kill an unsympathetic troublemaker? History shows us which option is most frequently selected. Good on England for showing restraint, but that doesn't change the fact that every command is suffixed with "... or else I'll kill you."
