I appreciate the videos. I'd appreciate them more if they included the approach to the deaths, as the context in which they occurred is but implied. Clearly there are pitched battles ongoing. I have seen IEDs used against the police.
It is impossible to know more than that there are violent clashes, and that people are dying, absent the specific context of the killings.
Regardless, it's a bad time to be in Venezuela. I am sure that many wish for little more than an end to the violence. That's what most people end up wanting shortly after an uprising begins. It was the case during the American revolution. Only about a third of the people were revolutionaries, the rest being either loyalists, or staying out of the way.
