BobbyPax, does it occur to you that there are rules and regulations about security that you may be unaware of? Do you know what happened to your socalled 'luggage that flew unattended'?
I am really not saying it all makes sense. I am not saying there are no holes. But do you have an alternative? Would you rather have no security at all? Just walk on and off?
Or do you prefer a 100% check on every single flight? Including a check on your private parts? The expression 'gaping open holes in security' will reach a different dimension then!!!
It's all a compromise.
