Well for one, there is no bigfoot to photograph. Two: your photo is not clearly depicting a jackal. There are photographs that are of equal quality that are claimed to be bigfoot. There are many videos depicting alleged bigfoots as well. (PGF for example) So the point is, if you can photograph it you can shoot it. If you wouldve been armed with a rifle, could you have shot the jackal?
The whole premise of bigfoot is just wack. It is ridiculous to think such a large (allegedly) beast would not leave ANY viable trace of it's existence. There would be tons of hair, scat and other sign of them were there to be such a large creature in the woods.
But that is all pointless... Bigfoot is not a real creature. It is a ghost, a faerie, a mermaid, a vampire. Spooky and scary big boogie man!!! Don't you know that bigfoot can dispense a wild pig with a slap against a tree with one mighty wack?!11oneoneone
If you're still confused, refer to this image. It explains bigfoot perfectly.
