The guillotine is used to make a statement.  
  
The gun is used when you want to actually get something done.  
  
&gt; it would just take 1 dedicated person to take them all out with the right amount of resources.  
  
Let's go small scale. What would it take for 1 person to kill 1 person, assuming they live within 500 miles. A thousand dollars, max? Not exactly hard now, is it? That is - If they actually WANT to do it.

I think another thing to consider is it is a lot harder to persecute the masses for a group action than it is to persecute a single person.

I think it is easier to get a group of people to do a thing (mob mentality) as it just takes a small group of strong believers and then they'll amass a crowd as they go that may or may not be loyal to the cause, you're not going to persecute the group that just dragged people to the guillotine, less you be dragged out too. On the other hand if one person assassinated all the oligarchs it would be really easy to prosecute them even if they have the support of the masses, so someone would have to step up to be the martyr and that takes a lot of conviction, which most people, even the sting believers, would have a hard time doing.
