On the last bit it is not wasted time, "you train like you fight" is a saying from every military in the world. Why do soldiers crawl through dirt and mud in the army? So it does not cause them to hesitate in a real situation, so you practice "yeah I may slip but that can not slow me down", yeah I may be getting muddy but I can't recoil. I need to run, hop a simulated fence like I would in a foot pursuit and THEN if I get the suspect corned be ready to fight regardless of the grading of the terrain. This is the stuff I was talking about in another thread when I spoke about the difference between the ring and real life (at least my real life.) Simply saying "such is life" and actually acting like that in real life are two very different things believe me. I will provide an example of this at the end.
Also LOCKDOWN involves not just low light conditions but bizarre light and sound conditions. Things look VERY different and can even be disorienting, in a real fight when you are on the "wrong side" of a spot light, take down lights, the red and blues and potentially a siren still blaring. Heck the CIA used similar conditions as part of "enhanced interrogations", now imagine fighting in them.
And both of these are actually try to never ever in 100 million years do them as a Police officer. In the second video I show you will actually see an officer on his back with the bad guy on top of him (bad guy in white t-shirt). The officer then reverses it and begins to stand because in both of these positions the bad guy both A. prevents you from getting to tools (in terms of my duty belt, taser, OC spray, spare mags and spare cuffs) and B. can access tools. As such the officer who uses these is making a cardinal error. If the officer is forced into this situation they want to rapidly swap to either an arm or leg control technique that does not have you in a position where you can't easily disengage (if necessary) access your tools and prevent access to them by the bad guy. btw concrete ripping up your knees? that is one thing I will admit you have to deal with in order to protect your tools.
As for an example...true story and it brings just about everything above into the pile.
1. It is after midnight and I see a guy I have been looking for on a warrant. I call it out over the in car radio. It is an urban environment with those crappy yellowish street lamps, half of them burned out, no such lights in the alleys. Also row homes with only occassional breeze ways you can cut through. Also this section of town dates back to pre-Civil War so you have these kind of fences all over.
2. I get out and start chatting him up because I am a bigger fan of
Dr. George Thompson - Verbal Judo Tactics & Techniques than fighting, it actually works more than you would think. I move to take him into custody and he played along until just that "right time" when he could make a break. Off to the races. My portable radio is "bonking" out because we were in a transition mode to new digital frequencies and a tiny switch got trip (f-you Motorola) so no one knows the foot pursuit has started.
3. down the street into the alley. cut through a breezeway. He hops a fence like that. I try to cut the pie to cut him off and do the same "ahead of him". Ooops the crap light, it was a gate and moved. luckily it hit my left cheek when I landed and didn't give me a prostate exam.
4. I finally catch up with him a block and a half away from my car. During this time my back up has found my car, my one pair of cuffs in the middle of the street but since the radio is bonking out is now running through the alley I was in yelling "JUANY!!!!!!!!!!!" trying to find me.
5. Now back then I was operating under my Aikido training that included ground techniques from Jujutsu. The SOB got my OC canister out. Luckily at the time we were issued the foam and I managed to knock it away and it just splattered on my cheek. if it was "spray" I would have been done. I then flipped him onto his belly and did what I should have done in the first place, slammed my knee into the small of his back to keep him down, but that transition from a BAD position to this freed an arm to come back and elbow me in the nuts before I got him under control and my back up found me.
The above is how a real world LE violent encounter happens. training inside on mats doesn't prepare you for this.
