I'll say it again. You can assert that he wasn't doing anything suspicious or illegal on his repeat visits to that house, but he disagrees with you.
His reaction on Feb 11 and Feb 23 indicate he was quite convinced he had been up to something he shouldn't have been, in there.
Now, English who is terrified of getting the same kind of treatment Bryant is getting, is cowed into saying absurd things like "the person on the other videos doesn't resemble Arbery" (when the guy is literally recognizably him, or at the very bare minimum someone who looks VERY much like him) and insisting nothing was stolen.
Well, in his interview he simply says he can't say when/where the fishing gear was stolen. He mentions it was transported in the boat. Okay, well - I think the period of time where the boat was in this open house that kept having people sneaking around in it, is a pretty solid candidate for the location where the theft took place.
He wants to avoid saying ANYTHING which could paint Ahmaud in a negative light. I can understand why.
