So, here's how it works then.
A government employee is apparently getting too close to the truth, whatever that is. He is killed in a car crash. The police, ambulance and perhaps fire department and the coroner are investigating the accident. The police don't like the look of the accident and begin to think foul play may be at hand. They notice the laser blast to the head of the victim which is confirmed by the coroner. The police conclude it was a laser blast from an alien space gun - the coroner agrees, he's seen many of these laser blasts before, especially with government employess.
"He must have got too close to the truth," admits the coroner. The police and ambulance drivers nod in agreement.
Suddenly, a black sedan appears from nowhere with two men in dark suits and sunglasses. The ambulance driver notes that it is nightime. They flash their alien police badges and state, "We'll take it from here."
The two men in dark suits tell everyone on the site not to say anything about the laser blast to the head and that the victim died of natural causes, in a car crash. Everyone nods in agreement.
"Yup, that's good enough for me," says the coroner as he fills out his report.
Is that how it goes, Mikey?
