PROTECT My RIGHTS!

In the article "Protect Our Right to Anonymity" it basically talks about how a police officer installed a GPS device on a suspected drug dealers car with a warrant. In my opinion I believe that is invading his 4th amendment and shouldn't be allowed to use the device in court. I believe this is invading his private because no one expects a GPS device to be with 24 hours, 7 days a week. It's just not normal thinking. It also is installed WITHOUT a warrant being they had NO permission to do so. If the officer is allowed to use this device in court against the suspect, it will give officers the right to install devices on everyone else and that's not fair.
