Dear Fellow Mudcats/MudTomcats/Mudkittens...

As I did not find this song in the database, I want to add it.
But there is one word I can't understand although I listened to the song many times.
It is marked bold, see below. I wrote the word as I understand it,
but I can't find it or anything similar in any dictionary.
Can anyone help?
Another question: does anyone know what the acronym "CS" stands for?
I know it is some kind of tear gas, but not what the CS stands for
My guess is something like chloride/sulphur.

The song is sung by Mick Moloney on the 4CD-Collection
"Irish Folk Favourites"

Belfast Town

We've barricades and gelignite and gunmen walk the streets
We've CS gas imported for the hungry kids to eat
Our towns and knells are a castle now and the waves begin to pound
And I'll tell you, John, I've oft time longed to leave old Belfast town.

Oh Belfast is a city where decent men are few
Where drums and guns have mesmerized the working man, it's true
Where democracy means impocracy (???) and corruption does abound.
And I'll tell you, John, I've oft time longed to leave old Belfast town.

For long we've been exploited and I have asked why
That men without compunction were allowed to bleed us dry
In many a filthy tenement in districts fallen down
And I'll tell you, John, I've oft time longed to leave old Belfast town.

Our minds are filled with poison and I fear it is too late
To wipe our walls of malice and the words that speak of hate
For freedom has been banished now and honest men put down
And I'll tell you, John, I've oft time longed to leave old Belfast town.

Oh well now, John, you've been and gone around the world to see
And have you found a country where the working man is free
Where there are no grasping landlords nor forces of the crown
Ah, tell me, John, and I'll be gone far from old Belfast town.
