Police Fatal Shootings: More Common or More Accessible?

It seems to me that we hear about fatal police shootings way more often these days.

Why do you think this is? Do you think these shootings are more common? If so, why? Or could it be that we hear about them more due to the inter-connectivity of social media? As in, do you think that social media is simply broadcasting an occurrence that has always happened, but we simply didn’t hear about it as often?
