gun sales records/ATF/toll roads....
I'm a bit leery of a govt based record of firearm sales or a claim that any records would be destroyed in 24hrs.
To me, it's like the govt(local-state-federal) saying they won't use toll road or highway camera records in criminal court cases/criminal investigations.
I've seen media events where they HAVE used these pictures or documents to ID someone.
In the UK, they are more strict about destroying traffic camera records & they can't admit them in criminal court actions.
Speed's fine, but accuracy's final.
