When I was doing my legal research on these issues in the wake of the RBS demolition action, a lawyer told me that there is a process to legal eviction: that a legal eviction notice (explaining the basis for the action) must be served with some sort of grace period for the tenant to make right or make alternative arrangements.
It doesn't sound like that's what's happening in these cases, though - it sounds like the fuzz comes in and serves an immediate eviction notice, with gratuitous confiscation of property.
There might be a provision that a grace period is not warranted in some cases of extreme exacerbating circumstances, and the (alleged) sexual slavery of poor trafficked victims might qualify there.
If this trend continues, I'm thinking of contacting the ACLU to see about exactly how legal all of the shit-storming is. Assuming that the/a lease-holder is an American citizen, the reality of Constitutional rights might trump baseless allegations of human trafficking/sexual slavery.
Let's all keep informed here.
