Thats the job of the POLICE: validate the information BEFORE getting the warrant and DAMN sure before busting down the front door.
Both should happen.
Ha, quite possibly true; but I put more (blind) faith in the police than I would a KNOWN element of crime (informants).
Though, I don’t recall any blow-back from the Duke lacrosse, or Brawley, or...Hell, women falsely accusing their spouses of abuse/etc. during divorce would fall into that category IMHO.
Course, I also believe those ‘in power’ should be held and sentenced more harshly too....
