I'm going to refrain from adding any personal commentary for now but I heard a podcast recently that was REALLY excellent and brought the perspective of both civilians/victims and the police force ...
Listen to this (it's 2 parts) and then I'd be interested to hear your impressions and reactions to it. It's not specific to social media it is more focused on LEOs but social media and 24-Hour news most certainly is a major factor (oops I said I wouldn't add personal commentary just yet lol).
