Did you reply to the correct thread? Since your reply makes no sense when applied to my thread response.

The logic I put forth does not support giving the police more power. I simply state that having undercover officers has some good to it. Any power can be abused and thus needs checks and balances. If there was a better way then I would support it... And don't think I believe in the whole: if you don't do anything wrong then you have nothing to hide crap either. I believe in privacy of public citizens.

Name calling tells me your young and you will learn in time what it takes to keep a civilized world together.

So your saying that when police use undercover agents to bust kiddie porn rings, dangerous drug production labs, terrorist type groups and other similar things that are bad for society that you would rather they didn't bust them using a method that allows them to potentially find a larger number of members than those they would have caught by doing a single raid on a facility?

And to the point about police safety, I think anything that keeps anyone safe is a good thing. There is no need to point out there are more dangerous jobs. Its like saying that the taxi driver doesn't need a seat belt because the construction worker has a more dangerous job.

Hydrogen peroxide powered rocket packs fly for around 30 seconds, because they have a specific impulse of around 125, meaning that one pound of propellant can make 125 pound-seconds of thrust, meaning that it takes about two pounds of propellant for every second you are in the air. Mass ratios are low for anything strapped to a human, so the exponential nature of the rocket equation can be safely ignored.

A pretty hot (both literally and figuratively) bipropellant rocket could manage about twice the specific impulse, and you could carry somewhat heavier tanks, but two minutes of flight on a rocket pack is probably about the upper limit with conventional propellants.

However, an actual jet pack that used atmospheric oxygen could have an Isp ten times higher, allowing theoretical flights of fifteen minutes or so. Here, it really is a matter of technical development, since jet engines have thrust to weight ratios too low to make it practical. There is movement on this technical front, but it will still take a while.

I think it may be up to web developers (me, you, and the other guy) to use the newest standards that are supported by the other browsers (Opera, Firefox, Safari) and to stop supporting IE to any extent other than basic page layouts. I know its often dictated by business to support IE, and you still would be, but not to the extent that it has been. Telling people that a site will be better in a alternate browser may be a good choice in this as well.
