My first reaction re: concert security was to question the sanity of the staid Swiss in allowing entry of Bieber and Celine Deion along with their enourages for any reason.
Having watched events from the D.B. Cooper hijacking followed by Palestinian and radical Reds shooting at Isreal’s Lod arport, the increased “security measures” have all been illusions with great costs, enormous inconvenience, and degrading and humiliating searches of 99.9999% of its citizens. And like the Maginot Line totally ineffective against the inbreed sand peoples of the religion of peace. 50 years and counting of successive generations of politicians touting the next snake oil cure.
Time to stand back and tally up the number of dead, wounded, permanently disabled, and affected surving famiily members versus dead terrorists.
Fact is western civilization is losing the battle of attrition against the billion and a half insane unswerving adherents of the ROP.
Any talk of a “Ring of Steel” within a country’s borders is already an admission that the walls have been breached and invaders are free to murder, rape, and pillage at will. Custer, too, hand a ring of steel at Little Big Horn.
A European example: Hitler was always decreeing this or that place was now a "fortress" ringed by steel. Each one was breached or bypassed to let wither on the vine.
