2 things...
I only donate goods to to people now via local community, where we have to meet f2f so they can get their goods. Or, something similar where I can see the direct benefit.

Majority of charities/non profits always have a founding cause, look at their business license to see who holds the cause, lots of times you'll find a liberal owner who is using it as their tax write off...example: George Soros...

It's sad that a tragedy such as this, has brought out the worse in everybody, and by the way, the more shootings...the more gun control! Nobody sells guns like the democrats.
