DHS employees working its Immigration Advisory Program and/or its Joint Security Program have local official complicity when it comes to DHS' ability to operate abroad.
Will the British government tell the US that such programs should be scrapped in the UK and make the US stop doing so on British soil even if supplied with evidence of US discrimination based on ethnicity and/or religion? I'm not holding my breath in expectation of the British PM really pushing this matter in a meaningful way.
