not quite, im sure it is all in the small print
this is just like when the cops have a suspect, and they tail him to see if he doesnt throw out a coffee cup
if he does, they pick it up and run the DNA off of that
same thing
(also one of the reasons i refuse to do those DNA tests, i dont want to be in a database)
i used to walk to middle school, it was about 2 miles, then bike to highschool, that was 6 miles on way
never ever had a snow day either
