This allows the government to hack AN UNLIMITED NUMBER OF COMPUTERS if they have a rubber stampped warrant from a judge who has no understanding of what they are signing.
I would assume that a judge would have some common sense. A warrant might say "All computers own by XXX person" or "all computers at XXX location." I doubt that a judge will sign a warrant for "all computers in Utah."
What is the alternative? "Whoops, we got a warrant to search five computers, but all of the illegal stuff is on computer #6, so we have to let this criminal go?"
Judges had to go through law school -- they are generally not stupid. I bet that most of them even own a computer or two.
