14 Killed in anti-government protests in Nepal

Might be the wrong reasons, but highly skewed and externally controlled social media do not necessarily mean bastions of free speech, they have shown that powerful group with right incentives and structures can capture and influence perception. Everyone has biases and social media will reinforce or amplify them if an external adversary uses in a targeted way.

Also while free speech and protests are important, the nature of protests or certain elements fuelling fire in the resentment can lead to these becoming completely out of control and destroying property or harming passersby. Sometimes pure anarchy is the goal of routine rabble rousers who use this opportunity. So I will go out on a limb over here and say no one over here really knows what happened in the sequence of decision making by the police and there may be some instances where certain actions may have been justified to avoid further escalation.
