Just readin the Indo (need registration to read - free) that more than 200 non-Irish recruits passed the aptitude test to join the Garda. And half of them were Chinese!
I was doing a search on more news about this and came across this, it's about Gardaí learning Mandarin. Some of the comments are a bit nasty on the end though. It's an ideal world when immigrants knows the English language, but when as more folks come here, the community gets bigger, they will just keep to themselves, and some might not speak English at all even though they have lived here for a long time.
The search also brought a Garda doc to my attention. Very interesting on how they should approach multi-ethnic people.
