loved the movie but one thing i always thought was stupid
is when the cops in town thought that Henry is a terrorist simply because he had security cameras around his house and several monitors the computers wouldn't have had anything on it that would lead them to believe they were terrorists and based on the fact that henry had a software that could purge the internet of anything with John's picture in it would mean that they would have never been able to get into the computer in the first place
on top of that they had no legal reason to search there house. no judge would have signed off on a search Warrant. not even in a small town. even than its not that small of a town it looks like a pretty good size town that likely didn't have backwoods judges as in the judge would know the law and not just be there because everyone knows him.
