64 terrorist attacks in the UK reported by ⁦ @Europol⁩ last year - more than in the other 27 EU countries combined! https://www.europol.europa.eu/activities-services/main-reports/european-union-terrorism-situation-and-trend-report-te-sat-2020 However ...

56 of those 64 were “ethno-nationalist and separatist” (in other words, Northern Ireland-related). Dissident Republicans accounted for all but one of the attacks in that category across the EU./2

And don’t assume from this map, despite appearances, that there were no arrests in the UK for jihadist terrorism in 2019. It rather looks as though the UK, for some reason, continues not to allocate its arrests (281 last year) between different forms of terrorism. /3

Though since the Home Office recorded 280 terrorism arrests last year in GB alone https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/869780/police-powers-terrorism-dec2019-hosb0720.pdfand and the PSNI a further 147 in NI https://cain.ulster.ac.uk/issues/police/docs/psni_2020_stats_security_2019.pdf, the figure of 281 UK arrests in the first graphic should surely have been 427? /4

I seem to remember rapping the Home Office over the knuckles when @terrorwatchdog for exactly the same error /5

The TE-SAT report is still an informative read, showing a decline in terrorist attacks in Europe over the past three years. /6

Deadliest last year were the jihadists, with 10 deaths and 26 injuries across the EU. /7

Terrorism continues to be a dangerous and unpredictable phenomenon – it has killed on average five per year in UK this century, and could have killed many more. /8

But it’s hard to argue that terrorism is uniquely dangerous or threatening https://www.daqc.co.uk/2018/10/26/the-fly-in-the-china-shop/. /9

Here endeth the lesson. /10
