Yes, it is sinister

From The Guardian:

Donald Trump wants us to associate immigrants with criminality. That is the reason behind a weekly published list of immigrant crimes – the first of which was made public on Monday. Singling out the crimes of undocumented immigrants has one objective: to make people view them as deviant, dangerous and fundamentally undesirable.

The very idea is sinister.

Since the start of his presidential campaign, Trump characterized brown-skinned immigrants as criminals by painting Mexicans as rapists and Muslims as terrorists. This fear-mongering has continued into his administration, and has expressed itself in unprecedented policies.

Trump has gone so far as to create an office called Voice – Victims Of Immigration Crime Engagement Office. An expert on concentration camps has already pointed out that the weekly list of crimes bears deeply troubling resemblances to Nazi–era Germany, where Hitler published Jewish crimes...

Reading the report, one is struck by how the alarmist rhetoric of Trump and the Department of Homeland Security doesn’t quite fit the nature of many of the crimes that are listed. A high number of them are for non-violent offences such as drug possession, driving under the influence of liquor and traffic violations. 

No other Republican candidate was so brazen as to actually encourage xenophobia for political advantage, and it was pretty outrageous that they, and the media, didn't attack it more during the campaign.  (Or now.)
