What makes you say that one day our liberties and rights will run dry?
To put it very simply- History. Look at the past, look at the end of all great civilizations. Now go back 10-20 years before they fell; now look deeply into our present. All good things come to an end; and, America is unfortunately not infallible.
We as a people have had it very good for too long. People have gotten lazy and blind to corruption. The Romans didn't realize, or care, they were getting screwed until Caligula started rolling peoples heads (literally)
Our rights are slowly being pulled from us. The constitution is constantly being loop-holed, taxes and fees are constantly going up (the impoverished can't fight back)
Study your history. Our world is not much different now then it was 200 years ago. Little more round and a lot more silicon but that's really it. People are still stupid and sheepish. And people are still greedy.
Unless some things pull a complete 360; we are all in for a wake up call. Parkour will very helpful when it happens
He's completely correct, at least on a basic level. Most people probably would say no if they were asked if the United States will exist for a million years as a country. Obviously then, the US will collapse at some time. But, will it last 10 more years? 100? 10,000? Who knows. Also, if there is a collapse, it's easy to posit that it won't be on a happy note. We won't just be bored of existing as a country and dissolve it. There'll be some crazy sh#t going on, and lost of rights/liberty will surely be a part of it. After all, those are only guaranteed by a protective [governing] body. It could be conquered in the next 10,000 years as far as we know (rights may or may not disappear in this case, but they'd probably change).
There's much to be seen on the rest of his argument, though, but I'm sure we all know what he's talking about in regards to that.
Back on topic:
I know some people have worked with the military on parkour training and techniques... I can't see why the police wouldn't do the same. Does anybody know of any
active sport, activity, or fighting style where the person stays on their heels? As far as Rafes's point about the shoe type being the deciding factor, does anybody know what the military teaches? I'm sure their boots have some extra heel too.
