Is it any wonder that so many people believe in conspiracy theories when they grow up with every adult around them (including, apparently, the police) conspiring to *make up a person with magic powers*, just because they think it's fun?
If you get so far as to collect a DNA sample, you should get to know the secret,, not have the police send you fake evidence.
More seriously, I don't think that really leads to conspiracy thinking, but there certainly are interesting parallels...
