A 30 year old police woman shot in Wis. yesterday. On the news the tactical swat team had AR-15's. Choice of tactical SWAT teams. Not a hunting rifle...... an assault rifle......AR-15 .223 caliber assault weapon. Hey Wayne La Pierre. Probably used this little .223 cal so they would not hurt anyone. Ask the Vietnam vets the carnage that a .223 can cause. Being a light bullet. It is designed to cause damage. Hit bone and ricochet. Could hit you in the knee,bounce 2-3 times and come out your chin! People laugh when a doctor says that he can tell the kind of weapon someone was shot with. A .223 tells its own story the way it travels. Cannot argue that.
