I may be flamed for this, but this incident, as well as the MiG collision, the near collision between Russian aircraft and a BA flight over the UK in 1997 and the incident where an Aeroflot crew allowed a child to take the controls which resulted in a crash with 100% fatalities, leads me to suspect that a lot of Russian aircrew tend not to show the same professionalism as those of many other nations.
And with regard to shoot downs, I believe there is a long list of unarmed aircraft, military and civilian, that have fallen to the guns of Soviet fighters while going about their day-to-day business between 1945 and 1991, naughty or otherwise.
