Do you think fringe events really occur?

regarding events like on the tv show "fringe," do you think these events actually occur? do you think the government covers things up to protect the public at large? please discuss.Do you think fringe events really occur?
Fringe is even more fiction than fiction. However, governments do keep secrets from the public, for better and for worse.Do you think fringe events really occur?
yes, in fact, i'd be surprised if this never happened. if you look at the 'alien spaceship crash,' ( not sure which one, but when Stalin was in power) using some of the data from the incident, it almost seems if it was intended as psychological warfare. Russians send surgically altered bodies to crash into america, and freak out americans. hysteria ensues. im not some conspiracy theorist, but 'fringe' event with government cover up would generally benefit the country rather than harm it.
