With eight days left on the legislative calendar, Gov. Andrew Cuomo has introduced a “red flag”-order bill that adds teachers and school officials to the list of individuals who can ask a judge to remove firearms from someone exhibiting threatening and violent behavior.

Letting educators file for gun-restraining orders makes sense, and four other states are also looking at it. But it’s most important to get some red-flag law, so that at least family members can intervene.

But the gov’s picking fights rather than finding a way to get it passed, saying: “Republicans in Albany have recently been mimicking the Republicans in Washington, and I think they would not support the bill now.”

Yes, state Senate Republicans are the main holdouts. But a narrower bill from Sen. Brian Kavanagh (D-Manhattan) might still triumph: It passed the Assembly with bipartisan support. And it made it out of the Senate Judiciary Committee by 19-3, with an “aye” from Sen. Andrew Lanza (R-SI), who chairs its next hurdle, the Codes Committee.

Maybe Cuomo’s version can pass in time; if so, great. But the key is for the gov to use his considerable clout to make sure New York joins the eight states that have enacted red-flag laws since the Parkland HS shooting.

Don’t make the perfect the enemy of the good.
