The Computer Fraud and Abuse Act. And I can assure you the DOJ & FBI are more than capable of collecting evidence to aid in prosecution. The problem is the criminals often located in jurisdictions that “look the other way” with respect to cyber crimes committed against companies and people in other countries. So prosecuting the criminals is a whole lot of paperwork for a whole lot of nothing to happen. It’s not as though Russia or North Korea are going to extradite their own citizens to the US to stand trial.
yes they are, but they don't answer when you call 911, do they? local police fumble around with this kind of thing every day, and crimes go unpunished thousands of times a second, every second, of every day.
don't know the first thing about how to even collect evidence to aid in prosecution.
don't know what crime has happened.
no one died.
probably from another country and "that ain't my jurisdiction"
lazy
etc.
