In 2016, UK shooter and popular YouTube gun channel personality Callum Long-Collins told the BBC, “Being British and a firearms owner, it almost feels illegal to have any sort of opinion on using guns for self-defense.” The comments appear to have been proved correct. According to an April 23 article in The Times titled, “Gun licences stripped from shooting activist over YouTube comments,” Long-Collins told the publication that he lost an appeal to have his firearms licenses reinstated with the primary reason being the content of his YouTube page, EnglishShooting.
