what seems to be a huge question is how do you know someone is "radical" in a free society??? If I post distain for our government over the interwebs, am I subject to round the clock government intervention? in a free country we can express our opinions without fear of punishment. so this becomes tricky when things get posted, like this shooter apperently did. I cant blame those in power for not arresting this guy pre incident, because how does anyone distinguish a post or tweet between an actual physical threat??? its impossible. so do we arrest anyone on the spot that posts distain for our country, our people or our government??? if thats the case we ALL lose freedom. we can and should be able to say anything we want. acting on that is obviously a huge difference however. that being said, i think canada should adopt open carry laws. take the burden off police and military. let us show how we WILL protect one another in this great country. and drifter great post on that video. man thats a overwhelming moment.
