I travel in Chicago all the time. Been driving there for 35+ years, never been sent off into a bad neighborhood due to a detour.If you are traveling through Chicago,and you take the wrong exit,or an accident closes the interstate,...say it's late at night,your car breaks down in the wrong neighborhood,ect.ect. You may well wish you had exercised your constitutional rights in spite of the criminal rulings of the filthy politicians in Chicago!
If you practice it's closer to 6 seconds.You can still carry your unloaded pistol with a loaded mag in a fanny pack on your person. If you are about to be attacked how long does it take to load and be ready: 10 seconds, 15? Do it legal and you're still okay. After all, this isn't Ohio!
