I haven't read the whole thread, but having looked at the video Bojo looks knackered. I don't think he pocketed the phone deliberately, he was just distracted and wasn't thinking straight. He didn't handle it well, but that doesn't make him a monster.
Bojo is in his 50s, so maybe he struggles to see such things without reading glasses, and doesn't like wearing them in public (vanity) or didn't have a pair with him.
I hate it when someone thrusts a phone at me and says "Here, you must look at this!" I just think "Why? It's a tiny digital image not worth looking at." I usually glance at it out of politeness, and feign an interest so as not to hurt somone's feelings, but it's not the same as looking at proper photos. If the journalist had printed off a decent sized copy and handed it to Bojo, the reaction would probably have been very different, as it would have been much easier to see.
Also, it must get tiresome being held directly accountable for everything wrong with the country, as though you are personally to blame for it all. People seem to think the PM should apologise for every single thing that goes wrong... NHS failures, released criminals re-offending, schools failing, housing shortages, etc, etc. The PM cannot possibly micromanage every decison and aspect of government alone and is not all powerful nor omnipresent. Any PM is just a (flawed) human being, not God.
I wish Rory Stewart had won the leadership contest, he seemed to have more integrity than many MPs, but alas it was not to be. Bojo is not ideal, but if the tories win a majority I hope he will put a decent team together to get the country out of this awful limbo. I have no faith in Comrad Corbin and his mission to take us back to the 70s. I lived through them - they were dire.
