Ah yes, because a stadium with thousands of people is exactly as manageable as your backyard.
Also, saying "tase or shoot people" is ridiculous. Don't put those in the same category.
One is meant to neutralize, the other to kill.
Also also, I like how you disregard completely the point about how they're running - probably sprinting even. Which is again, much less manageable than your (honestly unreleated) example of "people that walk past my no traspassing signs".
Seriously, put yourself in the situation for just a second and think again how chill you would've been.
