Unless you have osteoporosis, the chances of a ball striking you and causing any sort of damage are very slim, even if it is Messi striking it, and he didn't exactly smash the ball as hard as he could have.
Laser pens on the other hand can cause serious problems to the eye and vision.
People need to stop making it sound like fans can do what ever the fu** they want and the footballers must be the shining example. EVERYONE, I repeat, EVERYONE should set a good example, regardless of your profession and how much you get paid for your work. If you walked down the road and shined a laser pen in a random persons eye, I hope that person turns around and puts you in hospital.
I know the person Messi struck the ball at was almost certainly not the person shining a laser at him, but he is still showing his disgust with the Real Madrid fans, and in my opinion it is something that needs to be addressed.
Don't give the generic bulls**t excuse that "he is a footballer, he is suppose to act like an angel" because no one, even a saint, should have to put up with undeserved abuse like that.
By saying that Messi's action was warranted due to the fans shining laser pointers at him you are essentially saying that world class footballers' behavior on the pitch should be judged at the same standard as the fans in the stands are judged for their behavior. That's just ridiculous.
That is precisely what I am saying and believe how things should be. I'm not saying Messi to act on the same pathetic level as the fans, I'm saying the fans should raise there behaviour standards. Everyone should be judged in the same way, regardless of your job, your profession, or if you are just a spectator. No excuses, no buts.
