i wonder what are the ballistics tuned to? more like penetrating rounds or more like varmint?
i could see both sides...you would not need much to disrupt a CNS organ so penetration should work well especially if working in trees, brush, glass etc. which would be likely.
on the other hand...
You can/should use deadly force as soon as you are in fear for your life or the lives of your family.
I would avoid those situations at all cost, because that is what it may cost you. If you live though the riot and saved your family (of course this should be your primary concern), you may...

If you have a gun for self defense you shall have night sights.
If you want a illuminating aiming device you should have one. It has its advantages but be aware of the disadvantages.
