institutional racism means that the government has an active agenda to hinder a group of people
this is no longer something that is supported by the US government. in fact, it is fairly heavily discouraged. illegal, even. police officers are obviously prone to corruption since they consist of a large body of citizens, and so, less-fortunate members of the force will always exist. it's not a good thing, but it doesn't mean the government is actively saying it's okay. it just means that people were given authority that don't deserve it.
