I think today's world, technology is the most important part of life and people use it for their most private uses. Tracking phones may sound like invading privacy but if Police use this in an honest and realistic manner, it can be so helpful in tracking criminals and collecting evidence for a lot of crimes .
I understand why the Baltimore police are using stingray phone trackers. The city is dealing with serious crime and a lot of violence, and citizens deserve to be kept safe. I think that these types of trackers should only be able to be used with a warrant though. Criminals do not deserve privacy.
Not only does this violate the 4th amendment is also prevents people from calling 911 (read the article).
If they want to use technology like this based on a warrant or probable cause then I would be OK with that. BUT only if it is designed so that it won't disrupt people's phone calls, at least so it won't disrupt people who are trying to call 911.
The current Wiretap Act accounts for government surveillance over electronic communications and it should extend to the use of cellphones. Regardless of what technology is used, the privacy of citizens should be paramount. The ongoing erosion of this privacy as the basis for the argument that it will help keep citizens safer is unproven and has more inherent risks than benefits. The police should not use this or any technology without following the proper procedures and getting warrants.
Law enforcement should not be using stingray phone trackers, because this is a privacy and civil rights violation. Police departments do not need to use this technology to keep citizens safe. If law enforcement has evidence to support an investigation, they can acquire search warrants through the courts to track cell phones. However, private citizens that have not broken the law should not have to worry about their phone calls being monitored.
