Paintball marker for home security

[BFG Central]

Has anyone considered using a paintball marker/ paintball gun as a safe form of home security?
They can shoot 20-30 rounds per second at 300fps and anyone can own one.
No one in there right mind would run at someone shooting that many paintballs at them.
The best thing is that your not actually going to fatally injure anyone so after things calm down after the SHTF you wouldnt be going to prison or worse.

Iv always thought that after things calm down local groups would start enforcing there own type of punishment on to people who seemed to step over them mark defending themselves.

Even now the laws have changed regarding self defense,
Burglars that are more than half way up your stair case are classed as a real threat now, Where as before they were a victim if you defended yourself and your family.

There are also plenty of different types of paintballs on ebay.
Iv seen solid nylon, soild rubber, glass balls coated in rubber, You can even get hollow paintball shell that you fill yourself.
Not that all of them would be classed as legal for use in the UK.

As far as im aware anything other than a normal paintball shot out of a paintball marker is classed as breaking the law.

The UK riot police have been issued fn303 markers manufactured by RAP4 that work at about 400fps and shoot weighted paintballs for crowd control.
