Unless the little the little green buggers are bullet-proof they will find me and most of my Texas neighbors pretty well prepared.
There are multiple stories repeated over many years of the following sorts of things with guns:
1. guns just wouldn’t fire; wouldn’t work—regardless of simiplicty of the gun.
2. guns have fired and bullets have been seen to leave the gun in very slow motion and then in a short trajectory fall to the ground a few feet ahead of the gun.
3. guns have fired and bullets have been seen leave the gun in slow motion or unseen at normal speed only to hit some force field between the guns and the ET’s and then fall to the ground.
4. similarly, bullets have been seen to bounce off a forcefield shield around the ET’s and/or their craft with not the slightest effect on the ET’s or craft.
5. Guns have become hot—too hot to hold.
