Quoting Alyssa's mommy [EBFT]:" Even if they were made beforehand, what do you think hearing that would do to a parent who lost their ... [snip!] ... tragedy? Sure they could just not listen to the radio at all, but I think for now those songs are better off not being played."
You can't just make every "bad" thing go away because they had to deal with a horrible thing.
It really sucks that this happened but they know that songs like this exist and that there are all kinds of shootings going on all around the country right now.
I understand the want to have everything that could remind them of friday to be removed but it's not going to change how much they are hurting right now.
Hell they probably aren't listening to the radio anyways.
