Ever heard of a Taser gun ?

I've been told having a bullet shatter your knee cap is one painful way to get arrested...Don't know where you live but around here the cops carry guns- and aren't afraid to use them.  Have you ever been in to a prison??  There are some big beefy dudes in there!!!

Cops are trained to deal with just such a situation................

4 of them,  against you, not a problem.

I doubt weight has much to do with resisting arrest, more like stupidity, police are well trained and I don't think weight or build deter bullets , tasers or pepper spray

The bigger they are...the harder they fall...

Evidently you've lead a very sheltered life, and you have some lessons to be learned yet! Too bad you wouldn't focus on more positive things...your life would be so much more productive and meaningful.

At 500 pounds it shouldn't be much of a problem for you to out run most any cops, is that your theory?

It is extremely doubtful you will find an officer of the law who exceeds 500 pounds.  That is way past morbidly obese to begin with.  
Should you be a criminal weighing 500+ pounds, it does not automatically mean that you will resist arrest.  If you are exceptionally careless with your own well-being, you might try such a stunt. (Remind me to tell you how my 6-1, 150 pound son resisted arrest....successfully, but at a great cost).
It may take more than one bullet, but I"ll bet being shot will bring down a 500 pound guy like he was a 98 pound weakling.  
You seem to have yourself preoccupied with large felons and police.  What gives?  

You'd most likely die of a heart attack trying to outrun them...heh...heh. Happy running!
