I never claimed it would, and niether did you. In fact you stated breakage to enter, and said they needed bars ( see your own words in bold)I know enough to know that 1/8 inch Lexan will not stop a bullet.
1/8 Lexan WILL make it damn hard to break in. Feel free to try again, but if you do, stay on point.The door did the job because the bad guys panicked and ran off. On a front stoop like that if they had gone either right or left and there are most likely ground level windows they could have broken and entered. Sorry folks this is the fallacy of multiple locks on your door. Unless you have bars or shutters on your ground floor windows they will not stop a forced entry.
So in reality you have 4 choices: 1) Arm yourself to protect yourself against a forced entry. 2) Have a secure safe room and be able to get to it. 3) Hide and pray they don't find you. 4) Have a security system with a loud alarm klaxon and visible strobe lights to scare off attempted forced entry.
That is good, since the feeling is mutual. *chuckles*I have no desire to live anywhere near you.
