Garda walking around Amsterdam with a bag with a laptop and Garda stuff....likelihood??? Low
Said Garda gets tempted by sex window lady...... Possible
Said Garda gets so caught up he leaves his stuff behind...... Maybe
Said Garda doesn't go back when he realised he forgot his bag.......hardly
Most likely scenario
Bag stollen from garda's hotel with money
Thief gets a hard on from the excitement and visits brothel
Leaves behind bag as it is full of police stuff
