Even if you have a gun, you may not be able to do much. They are prepared, you may be in sleep. If they see you holding a gun, they may kill you first.

Do you know there was a man in FL killed by police around 1:30 AM while police knocked a wrong door? He told a gun to open the door, once police saw the gun, they opened fire and killed him. Did the gun help the man, NO! He did not have a gun, he might be alive today.
