In December 2016, the Met's anti-cyber crime unit arrested a 55 year-old man on suspicion of "racially aggravated malicious communications" aimed at Gina Miller, the woman behind the Brexit court case. The arrest joined various incidents in 2016 that highlighted the proliferation of hate speech, yet it was one of the first to flag that there are legal implications of the 'post-truth' era that we are now apparently living in. The crux of the issue lies in the problematic nature of prosecution given that freedom of speech is generally considered to be one of the bedrocks of modern democracy.
