Malus 'John Downie', crab apple
Can apples really be poisonous? Theoretically, yes, but the hard outer surface of the pips prevents them being digested.
Meaning of the Name
From the Latin for ‘bad’ or ‘evil’ after its association with mankind’s fall from paradise. Note that the Old Testament does not name the apple referring only to the ‘Tree of Knowledge’. It is said that the original tree was, probably, an apricot but that was too exotic for northern climes and the point that temptation was all around would have been lost.
Strictly speaking, the crab apple is Malus sylvestris ‘John Downie’ with sylvestris, 'wild' or 'growing in woods', being the species and ‘John Downie’ the variety but the sylvestris is usually dropped.

In 2005, Kamel Bourgass was convicted of conspiracy to cause a public nuisance by the use of poisons and/or explosives to cause disruption, fear or injury.

Though Bourgass was found to have a number of recipes for producing cyanide, and chemical equipment was found at his home, there was no indication that he had actually produced any of the gas.
