U.S. House of Representatives Homeland Security Committee Chairman Michael McCaul, R-Texas, is getting ants in his pants over the Boston bombing probe.

“Every day that it passes, it gets colder,” McCaul said of the investigation into who detonated the bomb on Monday that killed three people and injured dozens more at the Boston Marathon.

C’mon, Mr. Chairman, you ought to know these things take time.

McCaul is a former federal prosecutor who’s no doubt been involved in some tedious investigations. It’s only been three days since the bombs went off near the marathon’s finish line. Federal, state and local authorities are pleading for public patience as they comb through what looks like a mountain of solid evidence that’s going to lead – maybe soon – to an arrest.

Meanwhile, McCaul and a few others are wringing their hands that the feds haven’t announced an arrest yet.

Perhaps they ought to consider one theory being kicked around by knowledgeable observers, which is that the feds have put eyes on a subject or subjects already, have been tailing them and are just waiting and watching for the right moment to nab them. Just maybe they have someone targeted and perhaps they’re going to spring a big surprise on that individual when he or she least expects it.

New media outlets already have blown their coverage of the bombing aftermath, reporting erroneously that the FBI had made an arrest.

McCaul is afraid the suspect is going to flee the country. OK, well, Osama bin Laden was holed up half a world away once as well. He’s no longer with us.

The bombing perp has committed a terrible crime. I’m willing to give authorities the time they need to complete a thorough investigation before dropping the hammer.
