doesn't make sense!

At the end everything fell apart. Why would pitt's lady friend sell him out to some cop?? He has always had the law after him and has killed dozens of people. But , when one cop explains he killed a cop and has fbi on him, she immidiatly sells him out " so he can live". Of course he wont live!! He would get the death penalty , or be killed because he wouldn't surrender! Also how can he take out all the guys during the little exchange, but cant waste harrison ford .... and he had the advantage of surprise! I liked Ford's character, but come on, how does him tapping his foot on wood make him realize there must be a compartment. I might believe it if the panel was hanging off, but he really had to rip at the thing. These things always piss me off, they throw away realism so the "good" guy can win...
