Thank you scipio, that is very interesting. So this superglue vapor will have no effect upon any blood that may have been in the barrel of the gun?
No if it did then it would not be able to be used to lift latent prints left in blood and a different process would have to be used if blood is a potential source of latent prints. But fortunately that is not the case. As crazy as it seems they have even super glue fumed vehicles.
There are little things that matter for instance there are agents used to enhace blood stains like amido black. If you intend to use water based amido black it is best to do it before super glue fuming because
super glue treatment has the potential to inhibit effectiveness of water based amido black. It won't always but it could whereas methanol based amido black is not affected so if amido black is used after super glue fuming then it is typically methanol.
There are all sorts of little rules like this but none of them have any implications for the considerations at play in the Bamber case.
