Donald Trump’s Twitter fingers need to be tied up, rendered inoperable … maybe.

The president went bonkers the other day when a man rammed a rented truck into a New York City crowd. He said the suspect, an immigrant from Uzbekistan, should (a) be sent to Gitmo as an “enemy combatant” and (b) face the death penalty.

Oops, Mr. President. You shouldn’t say such a thing, given that you’ve already called the U.S. justice system a “joke” and a “laughingstock.”

The president walked back his Gitmo remark, but is holding firm to his view that the NYC drug-ramming suspect deserves to receive the death penalty. Legal analysts suggest that Trump’s tweet on that issue might complicate efforts to prosecute this guy. It could make it easier for the man’s legal counsel to obtain a lesser penalty if, of course, he gets convicted of killing those eight people in what is being called an act of terror.

The suspect is a radical Muslim who came here legally in 2010 and then professed allegiance to the Islamic State.

As the New York Times has reported: Presidents are typically advised never to publicly weigh in on pending criminal cases. Such comments can be used by defense attorneys to argue that their clients cannot get a fair trial — especially when the head of the executive branch that will prosecute a case advocates the ultimate punishment before a judge has heard a single shred of evidence at trial.

Of course, none of these concerns about the president’s idiotic Twitter rampages is likely to register with the man himself. He doesn’t care or doesn’t understand the potential consequences of his actions and public statements.

Weird.
