As always too many coincidences as per usual, there is no such thing as that many coincides 💯🐒
According to my mind, its clearly visible from your explanation that two clips are different. Not identical. So its fabrication. I must say.
I worked in that area for over a year (a long time ago) and crossed that bridge many times. I highly doubt that the video of the guy getting up is legit.. It's odd that the video exists - I agree.. However, if this guy had gotten up there would have been many people who would have seen it imo.
There aren't really any prisons in that area and I would not have thought that any kind of prison rehab group would operate near London Bridge as it is a prime property site for business.
i have been to this spot like 5-6 minutes before the attack. later police came and evacuated everyone from close objects - myself too.
Thanks for the post.
