Yes, I believe that the US does abuse its power. The most public example of which is civil forfeiture. Police can use their power as law enforcement officials to seize assets they believe are involved in a crime and the owners of those assets have no or little ability to defend themselves or take steps to regain the items that were taken away from them. Another example is the high level of surveillance implemented to monitor communications. Police have the ability to use Stingray systems in order to monitor the communications of citizens without their consent. Over the years, law enforcement have been gaining more and more power to control citizens without their consent.
