Parkour (or free-running) is awesome!! I have some of those videos blogged to my stumble account.
Now that would make a good olympic sport..
It is kind of like watching the Matrix.
We need about 12 more guys like that with Kevlar and M4s. With good intelligence we could clear most hostile city in the world in about a month's time.
I think if the military isn't already training special ops guys and others how to do this, they should start.
Police should as well.
I have seen the videos on the internet, but have not seen or heard anything similar with my units or other units I deal with. At least most NATO countries’ forces always seem too "troop protection" based to seriously consider something like this. Meaning more body armor.

I have no idea about police.
