Let's assume you knew a married couple, non-Catholics who had four youngish children and stable or even a "happy" marriage.
But they were involved with a crime. What would you blow the whistle on them for, and how would you make the decision ? What factors would you consider?
Here are some examples of possible crimes of different natures so you can base your justification or demonstrate where and when and why one might tell on them versus when one would not.
1. They grow dope (Cannabis) in a state where it is illegal and sell it to adults and make a five figure profit (say $20k per year) which they spend on supporting their family. So they are not getting rich from this but they are subsidising their family. If you object to cannabis then let's assume they brew beer and sell it without a licence, though as far as you know do it responsibly and with regard to human health.
2. They run a legitimate business but fiddle their taxes and pay thousands less than they should. Not simply tax avoidance but tax evasion.
3. They are engaged in tax fraud where they are creating false IDs and invoices and claiming large amounts from the IRS in say welfare benefits. Not merely not paying taxes, but stealing by fraud money they have absolutely no claim over.
Finally, assume that they have been convicted and already spent 3 years in jail only to come out and access some squirrelled away stash of at least several hundred thousand dollars, which you are 99.9999% certain is from their crimes since they don't have other jobs. Do you grass them up such that they go back to jail for second stretch for money laundering or failure to disclose their assets after their previous conviction?
What's the moral basis for making a decision to grass someone up? Is there something like a just war theory to decide what warrants you snitching on them? Do you take into account the corruption of the government, justice system and the fact that any taxes paid are more likely to be spent on illegal wars than anything just and and good.
Someone on SD suggested that because money was "imaginary" and the financial system a gigantic pyramid scheme that no objective moral evil was being done by them stealing millions when the government prints hundreds of billions to bail out the banks. Do you agree with this line of reasoning?
