Perhaps we are starting to expect too much in the way of security from applications?

An application is a tool that is designed to provide functionality. The greater that functionality the greater the scope for misuse and abuse.

Whilst it is reasonable to expect due diligence from the development community, i feel that we are drifting into an "it wasn't me it was the cat wot done it" mentality.

Just look at commercially available security applications? Sniffers, keyloggers, password crackers and the like. Has anybody demanded "safe" versions of these?

I was in a local hardware store the other day, you know what? I didn't see a single "safe hammer", "safe chisel" or "safe screwdriver".

I would suggest that the only reasonable expectation of a tool is that it is capable of safely performing its basic functionality. Anything else and it is up to the user.
