guns and force fields

my friend and i were experimenting with a a few guns and push objects and the like today and one of them was a scripted object that makes the targeted avatar move towards the person shooting the weapon. now this is a neat and fun toy but one thing that struck me as odd was the script was allowed to move my avatar with out my preauthorization.
I was under the impression that in order to move an ave like this aside from being pushed you needed the permission of the avatar being moved.

then it got me to thinking that a great deal of greafing that goes on in sl is from people shooting others and pushing them a distance and even to far off sims. and why we dont have some kind of force field that we could choose to enable that would prevent any one one or any thing from moving our ave.
it almost sounds like such a obvious solution to a great deal of the greafing that goes on in second life that i was thinking that force fields have not been made available as an option on purpose.

so my questions are

can we get force fields ?

if we cant why not ?

and don't you agree that they would be very helpful in preventing a great deal of greafing?

edit: i know there are force fields you can buy but they don't always work a force field built in to the client is whats really needed.

crucial, this reminds me of several threads I previously posted to, including this one about the same topic. On one hand, being able to push objects and avatars have many constructive uses--on the other, as you rightly pointed out, the destructive uses to cause grief are unpleasant.

As you also prolly know, if you sit down anywhere, be it on the ground or on a cube or on a chair, you become immune to pushes. Some Resident-created "shields" actually function on this principle, using nonphysical movement to let you keep manuevering around without being thrown sims away.

I remember playing There, there was literally a "force field" option to stop being pushed! I know currently in Second Life, there is a way to disable all collisions (including pushes) but it is region-wide and not useful for avatar-specific needs.

There may be technical means to make what you describe happen more transparently--but what would really help is a more focused drive from those who want it a lot. An example would be a voting proposal such as this:
and if you've searched the SL Forums and bundled up lots of previous citations and references in threads to the same thing, please PM me the list! I will certainly share it onwards.
