Re: Security fasteners

What value "security fasteners"?  One can purchase "drivers"
for damn near any of them, cheap.
 
Is the intent to discourage *casual* disassembly (given that
anyone determined to do so can purchase same)?  Perhaps to
be able to argue (in a court of law) that the other party
took "extraordinary measures" to gain access to the internals
of your product (so, if he was injured in the process, it
shouldn't fall on your shoulders)
 
Or, the hope of *actually* preventing disassembly?
 
I.e., wouldn't a tamper-proof "seal" be cheaper and more
conclusive?
