Subject self explanatory. Given their high profile public status it would seem prudent for journalists to have some kind of weapon. Either at home or concealed carry.
Any statistics on the number of gun owners within the journalists ranks? Is Wolf Blitzer packing heat or is he just happy to see me? 
The vast majority of journalists are not high profile, but I’m not sure that carrying a gun was necessarily prudent even for those who are.
47% percent of Americanssay they own a gun, and I suspect the ranks of journalists are roughly the same.
I have to question your assertion that gun ownership would be prudent for journalists: owning a gun seems to make you more likely to be injured during an assault.

So it would seem to be prudent not to own a gun if one was worried about being the victim of an assault.
My personal guess would be that it’s lower than average, but I have no facts to back that up, other than anecdotal experiences of having been in the journalism industry and knowing a lot of journalists. They tend to be, in general, anti-gun (though certainly not exclusively so), and, while working in the field, carrying a weapon as a journalist is a big no-no.
As far as carry permits go, many of them probably live in places where they’re not available. Wolf Blitzer lives in Maryland, which doesn’t issue many permits. Any high profile journalists living in New York City, New Jersey, Los Angeles, San Francisco, Chicago or Washington D.C. would have slim to no chance of getting one.
From The Culture of Crime:
I’m a current and longtime journalist. Folks assume our profession leans pretty far to the left, but that has not been my experience at all. Our newsroom is fairly evenly split. I suspect that reporters who cover the cops beat and see a lot of violence & crime probably tend to be more in favor of gun control, but that’s just one group. Many of my colleagues are avid hunters.
Whether they are pro-gun or anti-gun, I suspect the vast majority of journalists would say it’s a bad idea to carry a gun on the job.
I would agree with you that the profession does not, at all, lean pretty far to the left. But I’d be willing to bet that, as a whole, it’s slightly left of the American public, as long as we’re talking news reporters and photographers.
IIRC, Dan Rather talked about this briefly in his book, “The Camera Never Blinks”. It occurred when covering the civil rights story in the American South.
Don’t recall the specifics, a person (or a group) threaten Dan and others reporters with violence and the situation was very tense. A fellow reporter(?) then pulls out a gun and reminds folks a price will be paid for hostilities. The aggressive folk conclude that Texan reporters are not to be messed with and depart.
Rather admits being relieved that the person did bring his gun, but it’s still a no-no in the journalism profession. And he’s been in even more dangerous situations since then without packing heat.
As for reporters being pretty far-left, my impression is that the owner tend to put the brakes on the ideological leanings.
In the same book, Rather also describes a nighttime break-in at his home, during the Watergate period. He went to the top of the stairs, and shouted something like “I don’t know who the hell you are, but I want you to listen to this”, and he racked the action of his shotgun - an unmistakable sound. Whoever it was cleared out in a hurry.
Rather didn’t know if this incident was connected to his network’s reporting on Watergate, but thought the timing of the break-in suspicious.
