Professor Amanda Haynes:

It is also important to say that these beliefs are not based upon some form of abstract notion. When asked, people had very definite, concrete reasons as to why they believed that was the case. Examples included gardaí saying something about Travellers or something specific about someone as a Traveller, that a particular garda was known in the community for stopping Travellers or the location of where an incident happened, for example, a halting site or a particular location where someone would be stopped coming in and out. This is not a belief without foundation.
