Will former Police Commissioner Bernard Kerik ever stop making his own tragic situation worse?

In what appears to be an attempt to prove that he violated none of the laws he’s charged with breaking, Kerik violated courtroom orders, a federal judge says, and tried to taint the jury pool for his trial, which was to start tomorrow but was postponed Friday.

Some way to restore his reputation.

The judge, Stephen Robinson, revoked Kerik’s $500,000 bail and sent him to the slammer Tuesday. Based on Robinson’s description, it seems fitting.

Robinson called Kerik “arrogant” for leaking sealed information meant to smear the prosecution — after he’d already been warned not to do so following a similar incident last year.

Kerik is accused of corruption, conspiracy and tax-fraud charges. He was indicted two years ago for lying in his 2004 bid to become secretary of Homeland Security.

Though he withdrew his name from consideration within a week, prosecutors say he’d already given false information about a mob-connected firm that worked on his Bronx apartment.’

Of course, Bernie Kerik is owed the standard presumption of innocence.

That said, it takes some fairly egregious behavior for a judge to revoke bail and lock up a former police commissioner on the eve of his trial.

And while Kerik may think tainting the jury pool is the only way he can beat the rap, it’s reasonable to wonder why he’d think that — if he’s innocent.

This is a truly sad moment for Bernie Kerik and for all those who believed in him. At his trial, he’ll have a chance to prove his innocence.

He might want to start by first showing he can obey a judge’s orders.
