The attitude of the OP is clearly outrageous and I hope that he or she will by now have come to their senses.
As for all the armchair lawyers (especially when they quote Wikipedia as the legal basis for their opinion
), I respectfully suggest leaving it to professionals to define to what extent, if any, the OP's behaviour is criminal or merely negligent. It's always hilarious to see people jump to all kinds of conclusions based on an isolated quote (often from Wikipedia
) and engage in "interpreting" the law.
In reality of course, the law needs to be read in its entirety and with precedent in mind. Often, terms are specifically defined in law to have a certain scope and meaning and to read it as a general piece of prose is simply flawed and just doesn't get you anywhere.
From a purely moral and citizenship perspective, my view is that the utter selfishness of the OP's attitude is highly deplorable. I'd be interested to hear from real lawyers
whether or not the OP has a civil duty of care with regard to the bag they picked up in error and towards its owner?
