Events such as these are occurring in places around the world.  For example, territorial and gang violence in the central African region, 1997, had incidents toward women which are not included on the list of exemplary behaviors. 2007 article 'Congolese women confront legacy of rape', http://www.un.org/africarenewal/magazine/january-2007/congolese-women-confront-legacy-rape.

Incidents in Central America, in the past few years, is another. 
But, do not assume that these on a worldwide plane, are all isolated events, and the perpetrators of one region are unbeknownst to another.

In France, the attacks on young girls is beyond acceptable.  What happens when the situation is not brought under control, other events happen, sometimes shrinking the severity of the previous event.  Read story here, Israeli flag on the site: http://www.israpundit.com/archives/53841 titled 'Muslim gang-rapes across Europe under-reported in press'.
What can the Muslim community do to detract from the substantiation for the story being written?
When the facts are facts, it gets tougher to establish credibility which contradict the claims.

Meanwhile, there are some Muslim Palestinians, that continue a plight for the removal of Israel from occupying what they consider their territory and theirs only, the referent, the term Occupied Territories.
Concurrent, is that some have the expectation of all those Muslim to join the plight, and recognition by all religions that everything they do is in the right.

--Needless to say, question arises about how much progress is expected of that plight when pictured directly respective to the incidents discussed here--

Gang-Rapes Committed by Muslims Are Deliberately Under-Reported by the Mainstream Media", from the site called 'Answering Muslims', http://www.answeringmuslims.com/2013/03/gang-rapes-committed-by-muslims-are.html builds on the israpundit story.

In India, even though similar events are happening elsewhere, there is universal consensus that, that is enough.  Irish woman reports attack.
Was her behavior perfect, as agreed upon by all scholars?

In some ways it does not matter.

Here is a report of the story: 'Indian businessman arrested in rape of Irish woman', at http://www.newsdaily.com/article/2c71ca877f8ad7cbdd0f760672577d97/indian-businessman-arrested-in-rape-of-irish-woman
 AP reports from historic Kolkata.  Ingredients of the story, meaning other events amplifying the precedence of the situation, is already in that article.

Quick history, in the past year in India, Irish woman attacked, Swiss woman attacked, 5 year old baby attacked, American woman assaulted in Manali.

Outcry has already been performed at high levels, in response to the New Delhi incident, involving a female assaulted on bus.

As a matter of information, many Muslim families that are adherent to their faith might not have their daughter, traveling alone, especially hundreds or thousands of miles away from their house, regardless of how noble the mission.  Rules of prudency regarding colored drinks, social invitations, so on and so forth, might have different angles.   Recently, there was an early teens aged girl, right here in the USA, that committed suicide and posted the event on Facebook after a reminiscent circumstance, reference to that event is Saratoga, Santa Clara County, California.

"A 17-year-old girl has killed herself after four boys... and spread a photograph of the assault, causing classmates and friends to taunt and cyber-bully her, her mother has said.

Rehtaeh Parsons from Nova Scotia, Canada hanged herself in her family's bathroom on Thursday after months of torment and, on Sunday night, her parents took her off life support."

Everyone has to do their part.

It is unfortunate that lowly spirited persons can affect the reputation of a country on diplomatic levels.

Very serious ostracizing of people that do these crimes is on the table.  Reported and unreported.  Any more stories such as such-and-such a religious affiliation of men gangs up on European woman, the highest authorities are going to get to the bottom of it.  This is whether a staged crime, a group of people pretending to be a religion to bring defamatory reputation and cause ill-will upon the religion, or whether they moved from their native land and feel that once they are in Europe, or in the 'west' they can behave any way they want to.
