Yes, lets allow the kiddies who already get away with as little work as 
they can in order to produce the most destruction they can, the ability 
to use these 'Security Systems' as a new tool for DoS attacks against 
their enemies.

Scenerio:

Lets say my name is: l33th4x0r

I want to attack  joeblow.cable.com because joeblow666 was upset that I 
called his mother various inappropriate names.

I find IP for joeblow.cable.com to be 192.168.69.69

I find one of these 'security' systems, or multiple security systems, 
and i decide to forge a TCP attack from 192.168.69.69 to these 'security 
systems'.

These 'security systems' then, thinking joeblow is attacking their 
network, will launch a retaliatory attack against the offender, 
192.168.69.69 thus destroying his connectivity.

Kiddie 1   Joeblow 0    The Internet as a whole 0
