Yes, conspiracy fever.

As you know (and anyone can find out at NARA), the FBI files - the raw reports - on the assassination are filled with hundreds (probably thousands) of people making bizarre claims about their involvement or having seen or heard something about it. To put it differently: police say that whenever a suspected serial killer is found that they are inundated with calls from people either confessing to the crimes (!) or accusing someone of being the killer.
It seems that before the internet unstable conspiracy-oriented people made phone calls to the FBI about the assassination; now they have their own websites.
