So just since these bats have become popular in the last few years there's already 3 instances of people getting hurt, Baseballs gonna be around for a long time and there's just gonna be more serious injuries.
Since 2001 there have been three instances of people getting hurt? 3? You're saying
this is the most pressing issue?

Since 2001, there have been 21,870 Major league baseball games (Regular season only, 162x30 /2= 2430 games per season x 9 seasons including 2001)
Now, statistics are difficult to come by, as MLB teams keep these things close to the vest, but there is a bit of a baseline to research how many spectators are hurt by balls.
One lawsuit I found reported that in a five-year span at Fenway, injuries caused by foul balls ranged from 36 to 53 fans per year. Multiply that stat by 300 professional baseball teams networked through Major League Baseball, and at minimum, you may have 10,000 fan injuries per year caused by foul balls.
Lets just take the bottom number and say each MLB ballpark has 35 fans
significantly injured every year. (This seems insanely low, but we'll use the bottom floor here. I've seen a fan beaned at almost every game I've been to) So, League wide, that comes out to ~
1050 fans per year are significantly hurt by the ball per year.(30x35=1050)
Times 9 seasons, that's 9450 fans.... and you're pointing to the three instances that a certain type of bat caused an injury?
I find it amazing that baseball didn't learn a damn thing from hockey, and put up more netting. They will when a fan dies though, which will be too late.
