I'm team indoor cats. People do shitty things to wandering cats.
At one time a 4 year old pulled our cat's tail (she apparently did that to her own cat who didn't mind) our cat really fucked her up and even her parents agreed the 4 year old should've known better.
I was like 12 at the time and really worried they would put down the cat for attacking the kid. But here cats have immunity.
Here people do shitty things to people that do shitty things to (wandering) cats.
When the house cat doesn't like you, you are pretty much fucked and won't get invited much 
So, terrorists could train a cat to kill political targets? 
Maybe,
It's weird though, plenty of stories about dogs being put down because they did this or that.
"We loved the dog but he kept barking and tried to bite the kids next door so he had to be put down" :'(
With cats it's like:
*someone opens the door, a cat rushes towards you, you can smell it has just taken a dump*
"Look, there's Sam, SAY HI to Sam"
"Oh uh, Hi Sam"
*you take off your shoes and hang up your coat and enter the living room, someone shouts from the kitchen*
"Is Sam on the couch? Do you want anything?"
*you confirm the cat is spread across the couch, purring and staring at you, a place to sit would be nice for starters.*
"Well that is HIS place"
*the owner indeed confirms the cat's place is the entire couch. You look for a chair but most chairs and kitchen tables are used as shelves or temporary storage units*
"Don't worry about the mess, just grab a chair"
*The cat stares at you from the couch as you try to grab a chair and the mail, delivery boxes and cat toys drop on the floor*
"Did you find a chair?"
*The owner returns from the Kitchen, you have succesfully placed a chair next to the couch. The cat moves his paws just about enough so the owner can sit on the couch but makes sure you can't*
"Come on Sam, why won't you sit on my lap or go outside so our visitor can sit?"
*The cat refuses the instruction at best and at worst pretends the owner does not exist*
If you're lucky the cat will eventually go someplace else, if you're unlucky the cat falls asleep or keeps staring at you.
The only play you have is to become friends with the cat so it wants to sit on your lap the next time you visit.
*Once the cat has accepted you, photographic evidence is collected to commemorate the moment*
