The TSA is worried about the suicidal thoughts of its airport screeners

The TSA is the biggest threat to our security out there! Anyone who has half a brain knows the security is like a full circle, which means people are screened going in, AND going out. Is it inconvenient? Yes, but ask them this, what is to stop an employee of a company, that requires complete airport access, ramp, aircraft ect. From bringing let's say for discussion sake, explosive devices, or firearms, and hiding them on a particular aircraft, that person's partner has booked a flight on that flight, goes into the restroom for example, retrieves the item, walks out of the airport and performs another act of terrorism, or even worse, takes over the aircraft once again and pulls another 9-11. The answer is simple, America's TSA security is a dismal failure of real security.
I have flown all over this world, and with the exception of the USA, when you step off a flight, you are all escorted to another security screening before being allowed out in the airport to catch a connection or leave. The USA is also the only country that travelers have to avoid, even just to connect with another flight to yet another country, why? Because there is NO security, so unless your a saint, brain surgeon or belong to some group we deam with a talent we can benefit from, dont connect in America, because you might just walk past security and out into our country. Oh sorry I forgot, there is no security to go past.
