I guess they wanted him to know how much everybody hates him.
And what it achieves is a demonstration that Britain is not yet a police state, that democracy is not dead here.
But we know that.
Funny you should mention the police. I was reading about the impact on the police. They were dealing with Trump's visit, the WC, and then the protests on top. That comes out of police budgets for dealing with the everyday things that impact people. And the accommodation that frontline officers got during the visit and protests were mattresses on a floor.
I dont think anyone can be in any doubt that we aren't a police state, and that we still cling onto at leats a veneer of democracy; we regularly have protests, there was an anti-Brexit one a few weeks' ago. But Trump is not the kind of person to be cowed by people hating him; like any narcissist it won't result in a period of self-reflection, but rage, hate and a determination to be even more himself and to do more of the things that people don't like. In that sense I fear the protests won't just be ineffective, but counter productive.
And the Trump baby blimp reminds me of the trend for signing petitions and then thinking that your bit is done; the crowdfunding for that could have been put into refugee relief or donated to any number of non profits Stateside, but instead we opted for a self-congratulatory empty gesture.
