It is dangerous, especially without warrants and massive data trails of who requested the data and why, who looked it up, what they checked and more. Not only just from the law/security side but from people in your position, probably at a security firm that some of this is outsourced to or a govt agency that has these capabilities.

For instance, take someone in your role or even a team of someone from enforcement and someone in your role, if 1-2 individuals get in that situation that are corrupt, it can turn into a blackmail or potential business espionage scenario. Since requests/warrants are being suppressed to keep a low profile, even finding out what and how information was looked up would be easy to pass for some scammers or organized criminals. Someone could sell access to information and start targeting many people. Scams could be run on wealth or small competitors suppressed.

The other side to this is, I wonder if you worked with anyone, or if people in your role, ever looked up information on people they know or potential competitors/enemies to use against them even if they did nothing wrong? What kind of oversight would be there to watch that, especially in the more underground operations in law enforcement or national security? Cops now in most places can look up anything on your phone. Are they doing it to family/friends/business people that they want to have some blackmail or upper hand on? Are they spying on people for their benefit, not for a crime? Probabilistically yes.

The gaping hole of security is the human, a few bad people with access to that data and you have some authoritarian powers that have never been seen in history to be abused. Giving individuals that much power will end badly, there is no way someone could control themselves if there is little oversight. If a law enforcement officer or security/intel professional has to provide no trail of that, it will be abused. It will be abused even with the trail.
