collecting evidence

What really gets me is this; the BFRO says they are hunting for bigfoot and collecting evidence to proof they exist. Here's the problem with that statement, the only tools they bring to document anything with is a "therm" and some  Gopro cameras. The only thing they are recording is what expressions they have on their faces when they hear a noise. There aren't any digital recorders hooked to parabolic mics or any other type of recording devices. So they aren't documenting anything. I used to watch this program until I realized they weren't capturing any evidence and documenting it to be revued later.
