In a lawful society, there are obligations and protection accorded to each member of that society. If a law is broken then there are consequences - that is the cause and effect. When there is conflict of systems across international lines, then my simplistic view is to each its own. We don't impose on another's jurisdiction and the expectation is mutual.
You are right, that is a very simplistic view. Should one country's laws only take into account the impact within said countries own territorial and legal boundaries irrespective of the harm done to others? Thankfully, few countries take such a selfish view, and most impose legal restrictions on their citizen's actions, even abroad.
If we dispense with the niceties if purely legal theory and look at reality on the ground, your view falls apart even further.
Do you think for a nanosecond that western governments would be swayed by your 'don't impose on another's juristiction' expectation if anyone was doing anything to deliberately and/or recklessly put their citizens' lives at risk, even if said activity is perfectly legal in the host country? Ever heard of renditions and drone strikes? One does not even have to wonder what the reaction would be if a Muslim country renditioned the survivors of Charlie Hedbo and/or levelled their offices with a Hellfire or Paveway.
Each member of society should have the liberty to make choices within the boundary of its law.
The arguement isn't and never have been about whether people should follow the law or not, but rather whether the law should limit free speech to protect people from harm when free speech is abused.
Charlie Hebdo makes fun of all religion including Christianity. As a Christian I don't like it but we learn to ignore it.
Well that's comparing apples to oranges, since there is no prohibition in Christianity in terms of using pictorial depictions as there is in Sunni Islam.
People all over the world have criticised, mocked and cursed Islamic beliefs and the Islamic prophets in print without causing people to loose their lives. Muslims are not any more or less easily offended as Christians, Jews or any other religious followers as many mainstream western commentators and media outlets have tried to imply.
The overwhelming majority take a similar view towards criticism and literary attacks as you do, so long as it doesn't violate a cornerstone of their faith.
The law have made exceptions before to tailor for religious beliefs, would it be going too far to just simply say, don't draw pictures of Islamic prophets?
Ultimately it is not the action of others but our reaction that matters and that is where responsibility lies. Being offended in my view is not an excuse no matter how you try to cut it.
Again, an extremely simplistic and narrow view, even from a purely legalistic point of view.
Going back to the 'fire' example, by your reasoning, the death and injury that ensues would be the responsibility of the panicked people rushing to get out rather than on the person who shouted 'fire'.
This is not to excuse rioting or arsen by any means, it is merely pointing out that as unfair and illogical it may seem to you or I, these are the realities of the world we live in. It is as pointless debating the reasonableness of Sunni Muslims' reaction to people making insulting pictures of Muhammad as it is to argue about how a panicked crowd should behave in a confined space.
And to be frank, in terms of the Muslim reaction, the west has got it easy, terrorism and all.
Muslims are only rioting in Muslim lands because their governents are all either too weak or too beholdened to the west to do anything about these cartoons. So the people vent their rage impotently on each other.
If the Muslim countries had western levels of wealth, power and democracy, they would be imposing sanctions and/or sending carriers to the French coast right now.
I suppose that's the thing that I, as an atheist neutral observer, find most distasteful - the west's trampling of Muslim values and beliefs seems too much like bullying for my taste. The views and feelings of Muslims are simply not even a factor to be considered in any of the debates I have seen on the matter. Its all only about western rights and freedoms. Because the Muslim world is too weak for its views to matter apparently.
That is the illogic of might=right, and that is not how the world should be run.
