Well, then you would be likely to believe that it was police incompetence that let Ruby get close enough to Oswald to kill him. It was possible but once all the facts about Ruby's connections to the mob were made known it became obvious that something else had happened. So, we shall see if such an important prisoner was allowed to commit suicide because of incompetence. For one, what did he hang himself with? He had been on suicide watch and when that happens they remove anything with which the prisoner might harm himself. So, even if he was taken off it, you think they would've allowed him to have something which he could hang himself with? And just by coincidence the video camera malfunctioned. I can't believe it, especially knowing how corrupt the government is.
