The truth is, and figures are not needed to show this, that concern in Epping is at an all-time high. I think I said before that it would be better for everyone concerned for the migrants to be moved out. It would relieve the tension felt, but of course, this would set a difficult precedent.
The Bell Hotel is not much more than an easy 10 minute walk from the town, certainly for a fit young person. Even the Assistant Chief Constable has acknowledged that the strength of feeling in Epping about the hotel is not lost on him. At least he understands the significant impact that the situation is having on people. There is little wonder that Epping residents feel angry or scared.
How high is high?
Before this, I doubt if there was much concern at all, despite the fact that asylum seekers have lived in that hotel for years. That's a very low base, so it wouldn't be surprising if concern has increased, so you can now claim it's at an all-time high.
PS. When you write of "Epping residents" don't lump them all together. There are plenty of Essex residents who don't feel anger or fear.
