Ths story from CNN says that Trunp is going to sign an executive order that forms a federal database on police personnel and keeps track of abuse complaints.
Trump doesn't have the authority to form federal database on police personnel and keeps track of abuse complaints.
There are restrictions on what kind of databases the Federal government can have regarding U.S. citizens.
In addition, if the Federal Government wants to created a new law enforcement related database they have to publish the specifics in the Federal Register and give the public the opportunity to review and challenge it.
And, it is Congress that has the authority by legislation NOT the president Executive Order.
WE DIDN'T ALREADY HAVE THAT?
Each federal law enforcement agency has its own records of disciplinary actions, etc... held in their "Personnel" offices.
But there is no complete/comprehensive data base for federal law enforcement personnel.
Additionally, there is no complete/comprehensive data base for local/state law enforcement personnel.... and it is likely illegal for the federal government to have one.
It is also unlikely that each state as any such database for all of the state level law enforcement personnel in their state.
It is the sort of thing that would be maintained at each "Personnel" office.
It might seem odd to some, but in the USA law enforcement personnel are citizens with all of their due rights... just like everyone else.
>>>One exception to all that
is that if a law enforcement person is convicted of a crime.
