It is perhaps worth pointing out that for anybody aged 21 or over convicted of murder of a police officer or prison officer in the course of their duty, the law already provides a starting point of a “whole life order” - i.e. life in prison without parole. https://twitter.com/crimelinelaw/status/1291019705008914437

The problem with introducing a mandatory whole life order for people convicted of manslaughter (which I think is what the campaign is suggesting) is that you end up with hugely disproportionate outcomes.

It means that somebody who throws a single punch, not intending to cause injury but resulting in a police officer banging his head and dying (manslaughter), would get a whole life order, whereas someone who intentionally stabs a victim to death gets a minimum term of 25 years.

I fully understand and appreciate the emotional drive behind this campaign, but those supporting it should think carefully about what it would actually achieve.
