Yes there are a lot of great tools out there for breaking into cars. There are a lot of great tools out there for cutting seat belts, getting into houses, cutting barbed wire fences, etc etc etc.
But how many people "know" what they are going to get into in our daily lives. I'm sure if the ex-cop knew he was going to have to jump into icy water to break through glass and rescue kids, he would have dressed appropriately, carried the right tools, etc etc.
But he did, he used what he had. Had he had all the tools necessary to cover ever task out there, he would have sunk when he jumped in the water.
Hind site is great. But you can't prepare for everything.
Reminds me of when I went to the Hazardous Device School (EOD School) at Huntsville AL. They made lots of fake bombs we were to de arm. One case, they would grab us out of a class room, point out a fake device and tell us we have to disarm it with what we had in our pockets.
Afterwords we had a debriefing. One Cop from NYC, just got up and said he was blown up. Instructors asked why, he simply said "you ever try to disarm a bomb with 35 cents and a comb".
I read all the time on this and other forums about people saying they would carry this, or that, and they always have X on their person. Heck I didn't carry that much stuff when I was humping the jungles of Vietnam for months at a time.
Fireman and cops can carry a lot of stuff in their vehicles, we carry what's in our pockets. I carry a Leatherman tool around the home place. Handy. I don't carry it when I go square dancing or to my granddaughters ball games.
If you carried a semi truck load of tools with you everywhere, some day, some time, you're gonna run across an incident where you need something else. Just ask your mechanic how many times in his job he has to stop and run to the parts store for some special tool.
I get amazed when I read these post, someone always said "he" should have been carrying X, or Y.
It just don't happen, you have to use what you have, and thats just want this guy did, and it worked.
