You tell me, I've no idea what you're talking about. Hit me with a number Scotch Mist.
https://en.wikipedia.org/wiki/Martin_NeyOn this link you will find a list of the crimes against young boys committed by Ney in Northern Germany over a 9 year period. The most recent crime in which he is implicated occurred in France in 2004 - the murder of Jonathan Coulom - broke the pattern in terms of location. However, in 2019 the French issued an EAW to Germany in order for Ney to be questioned further over Jonathan's murder, based on new evidence.
Statistically, Ney would neither have abused nor murdered young boys in France - but he may well have done. It's unclear as to why he appears to have stopped offending after 2004 - or maybe he didn't. The odds of a boy being abused in a holiday camp in 1990's Northern Germany were far greater than, say, Switzerland. It's possible that the public were not made aware of the risk to young boys attending such camps, hence what appears to have been a lack of vigilance.
In the Noughties on the Algarve, we now know that there was a series of holiday residence intrusions, in which the victims were young white girls.
https://www.theguardian.com/uk-news/2014/mar/19/madeleine-mccann-police-intruder-girls-algarve These intrusions do not seem to have warranted police making them public or issuing warnings through relevant agencies. Although none of the Algarve cases reported involved abduction or murder, it cannot be taken for granted that the offences would never escalate from just sexual abuse. Had Tapas 9 & other holidaymakers been aware of the increased risk to young white girls on the Algarve they may not have left their children unattended (all but one of the children were female) at night or even chosen Luz as their holiday destination.
