IMO the fundamental problem we have today isn't that the particular techniques are bad, it's that the system is easily gamed and incentive structures lead to law enforcement simply acting in bad faith a lot of the time. They just want to put you in prison, irrespective of innocence, and they'll use/omit whatever data points they can to do it.
The problem isn't the techniques, it's that law enforcement in America seems to now be built more around profit than law abidence... And I doubt increased surveillance put in for the best of intentions wouldn't ultimately become coopted somehow by these interests too.
