I never suggested that it would keep them safe.
I said that you would know that there are people there and they might be or about to be in serious danger. What you do with that information afterwards is an entirely separate conversation.
If it is in your power to have this information and you neglect to, that is highly immoral. If we're going to have this border policy then it is our responsibility to know the effects of that policy. Surveillance of this crossing where hundreds of people die every year is a moral imperative.
People are posting in this thread suggesting that having autonomous surveillance here is akin to pointing weapons at people. The suggestion is hyperbole and ridiculous.
What's really disheartening here is that the people that don't like our border policy would rather we turn a blind eye here guaranteeing that these deaths continue and in greater numbers.
