This has been covered before many times but in the interest of protecting our hobby I will answer, note I am not a lawyer and this is not legal advise, just my opinion but I think a valid one.
The problem with a dazzler is causing permanent damage rather than simply stunning an attacker.
But what if someone means to kill me, surely doing damage would be justified....YES, everyone has the right to defend their life so get a gun, don't take a flashlight to a knife fight.
Also there's a stigma with maiming people intentionally, it would be much better to carry a bright LED flashlight and a can of pepper spray than a laser with the intent to walk the fine and undefined line between temporary visual incapacitation and permanent visual disability.
But what if I can't get a gun or a carry permit......vote to change your local laws, it's your God given right to defend yourself and your Constitutional right to carry a gun ( In the USA ).
You can also look into a tazer, not a toy pocket shocker that will get you walking funny with a busted pocket shocker shoved up your ass but a real tazer.
Bright flashlight, pepper spray, tazer, an asp or collapsible baton if you are able to utilize it......this is what you need to think about if you can't or won't carry a gun, not a blinding laser, it's an old reference but I will use it again......it's like keeping a super soaker full of battery acid by your door......could you defend yourself with it.....Yes, would you wish you had not......Yes
But how is a blind man going to point me out.....stop it, cameras are everywhere.
I you may notice I mentioned a knife fight.....while knife fighting is a bad bad idea you can always carry a knife as a last ditch " utility item " and you would do better in court saying you were forced to slash at someone with a knife which they would be more likely recover from than a maiming with a laser or acid.
Best is to avoid trouble and failing that use all that you can to your advantage, element of surprise, knowledge of tactics, reasonable and acceptable force multipliers....... be sneaky if you need to, but not stupid, blinding with a laser is asking for trouble and remember people lie, someone only dazzled can complain of disability and you could easily be found liable with the stigma associated.
