CS gas into Cyanide?

I have no education in Chemistry but there is a hot debate in our country right now about the usage of expired tear gas (CS gas - 2-chlorobenzalmalononitrile or C10H5ClN2) in protests.

My question to you dear educated people is that is it possible for a 20cc (cubic centimeter) CS gas canister to develop a deadly amount of cyanide after five years?

The gas is being used against university people so I am unable to ask them because I might get a biased answer. Thank you.

I found a Spanish(Venezuelan) article which says CS gas produces Cyanide but in that research there had been 720 expired canisters used but no one had died.
