Specious.  As others have observed you need to be root to do that.
Squid, even if it is started by root, switches it's user id to a
configurable one fairly early on, in fact, if you are using the
default squid tcp/ip port then you don't need to be root to start it.
Normally squid runs as the id nobody - that userid being able to cause
a kernel panic then there is a problem.
