Your idea is a good one. And a simple one, at that. Surprising that the Patrol officer and his wife haven't done just that. Assuming, that is, that it matters to them. Sounds like maybe it doesn't.

They DID film them.  And Fox filmed them as well.  They put it on TV.  I saw it for myself.  What is that light the Army uses for night time?  It's all green. 

But Fox and this couple DID film the immigrants flooding over the border.

Night vision goggles, and they are (or comparable equipment) also available to the public.
