I don't know about the guns part of that but I can attest to the suicides. Seen enough of them in my work (when it's you who has to go pick it up after the police are done). Sometimes a real bloody mess.
Ok. You name me one gun that doesn't have a recoil
Some guns have little to zero recoil so your logic only proves that you have little to zero knowledge on guns and ammo as well as recoil. You're opinion is worthless.
The cop shoot outs are staged. There are no recoil in the guns. Obviously using blanks.
