Any SPS array is going to be viewable by anyone with a telescope. You'd
SEE them mounting a laser cannon long before the bad guy could fire the
silly thing.

The solution is hinted by my comment above - don't allow a government of
any kind to operate the SPS but instead give it to a for-profit
enterprise. Business guys won't let their expensive capital be used as
a weapon - no profit in it.

Everything the company operating the SPS array does (or any vehicle in
orbit) is open to inspection by anyone with a good telescope on the
ground. This is your solution to the 'using X as a weapon' problem -
shenanigans like this will be seen and corrective action taken.

I'll got a step further - any enterprise in the space access industry
might be advised to open their internal business up to public inspection
as far as they are legally allowed to. You can't do anything without a
paper trail, and this would include shipping to, and operating an
illegal laser cannon. If the public can see this happening, things can
happen to prevent it.

No, I'm not so far gone as to imagine you'd find an invoice for "1) Acme
X-Ray Laser" but the bits to assemble such would be visible if anyone is
looking.
