Tuesday, Bloomberg published a highly instructive, scrupulously reported story about the frequency of foul balls injuring fans in major-league ballparks.

Executive Summary: It’s probably worse than you think, and Major League Baseball could be doing a lot more to prevent such injuries.

But I’m afraid I must say, yet again, that there’s no "right" or "wrong" here.

Well, very little. MLB supposedly claims they haven’t studied the frequency of foul-ball injuries. If that’s true, I’m sure they’ve got their reasons — if they don’t find a problem, they can’t be sued as easily? — but either they’re lying or they’re willfully ignorant. Both of which seem sorta "wrong" to me.

But there are degrees of wrongness and rightness. Was it "wrong" 20 years ago to let your kids ride their bikes without wearing helmets? Was it "wrong" 10 years ago to leave your six-year-old in the car while you run inside the store for five minutes? Our standards change. Today, it’s acceptable to protect just the fans behind home plate. In five years, it might be unacceptable to leave anyone between the dugouts unprotected. And in 20 years, there might be netting from foul pole to foul pole. At this point, the teams are offering exactly the protection that we have demanded. And our demands probably won’t change until someone gets killed.

In the short term, you just wish people would pay more attention…

The Braves said days later that the child had returned home and was "€œdoing well." According to Laird, who spoke to the boy’s parents the night he was hurt, the father had briefly glanced away when Gomez pounded the ball. That’s not uncommon. Mets outfielder Eric Campbell said he often sees distracted spectators.

"€œI hate seeing people in the front rows behind the dugouts, especially with babies or little kids, because you know they’re not paying attention to every single pitch,"€ Campbell said in August before a game at Citifield against the Braves. "They’re looking at their phones, they’re talking to the person next to them. There’s 250 pitches in a game. To expect them to look at every pitch is probably unreasonable."

Every pitch, yes. But more pitches, no. In the short term — you know, before somebody gets killed and we demand more — parents should either stop sitting with their little kids in the really good seats, or they should start paying a lot less attention to their phones and their beer vendors. Someday the nanny state will step in and help. Until then, it’s up to us.
