How is this not terrorism?

The Guardian reports:

Merseyside police announced last week that 18-year-old Rudakubana, who is accused of murdering three young girls at a Taylor Swift-themed dance class in Southport in July, had been charged with two further offences – producing the toxin ricin and possessing an “al-Qaeda training manual”.

The force said the new charges had not changed counter-terrorism policing’s decision not to declare the Southport attack terrorism, and urged people not to jeopardise Rudakubana’s forthcoming trial with speculation.

So he burst into a Taylor Swift-themed dance workshop for children and stabbed 11 children and two adults, killing three children. He has a supply of ricin, and a study of a terrorist training manual.

Yet somehow this was not a terrorist attack!

Being terrorism doesn’t mean multiple people were involved. It is the unlawful use of violence in pursuit of political aims.
