How to cheat on your significant other and not get caught: Have sex with the other person only once (One night stand). Having a relationship will increase your chances of getting caught. Order room service at a hotel, instead of going to a restaurant. Love letters are evidence that can be used against you. Cover up stories include working early, working late, doing volunteer work at some place.
If you are going through a divorce: Don't hide large amounts of money in your home. Your spouse could get a restraining order against you. Hide your money, just don't hide it in your home. Don't deposit any suspicious checks. A private investigator could have mailed you that, to see if you will cash it at a bank account your spouse does not know about.
If you are arrested: Don't give cops your password to your phone. You have the right to remain silent, use it to your advantage. Don't touch anything cops tell you to hold, they could be trying to get your fingerprints on more items. If you get the arrest erased from your record, in the future if a cop asks, "Have you ever been arrested before?" say, "I have no arrests on my record." Do NOT say, "Yeah, but I got the arrest erased from my record."
Feuds with neighbors: Don't leave a note at your neighbors' door about the barking dog/loud music/hoarding of garbage with your name on it. This could later be used against you in court. Report people blocking your driveway under another name. If cops say you have to give them of recordings of your home security camera, tell them you are going to report them to the district attorney.
Traveling in your car: Have your car under a business name. Insurance under your real name. If cops ask, "What do you do?" You do NOT have to tell them the exact location of your job. You could tell them you make websites, own a company that owns investments, own a company that owns rental properties, are a online teacher or unemployed. If you are respectful to cops, the majority of the time they will be respectful back.
Warning about using a CMRA (Commercial Mail Receiving Agency): I put the address of a UPS store and my mailbox number on my California ID application. I did not put my home address on the application. They scanned my ID at a pawn shop, the screen showed my home address. That's because the big business CMRAs (The UPS Store, Postal Annex, PostNet) will keep your name and home address on a national database. Some websites will not ship to a big business CMRA. It costs more to rent a mailbox from a CMRA than from the post office. The application (Form 1583) asks for 2 forms of ID.
Warning about using a PO box: You can't open up a bank/credit union account with just a PO box. The post office mail forwarding is less reliable than service you get at a CMRA. Lithium batteries, airbags, ammo, explosives and gasoline can't be shipped to a PO box. The post office will put junk mail in your PO box. The application (Form 1093) asks for 1 form of ID and proof of residency (Lease, home insurance, vehicle insurance, utility bill).
Untraceable PO box: Rent a PO box, then when you move don't update your residency. Or use a passport along with a proof of residency with a past address or from another state.
Untraceable PMB: Rent a PMB from a CMRA, then when you move don't update your residency. Or use passport along with an ID with a past address or from another state.
Move to another country if: You are drafted to go to war. A judge orders you to pay "Forever spousal support". You can escape debt by becoming a permanent tourist. That means living in another country without any residency/citizenship. Getting residency/citizenship often requires a check of your credit.
Oh yeah, and one more thing: Go to private school, not public school. Don't put your resume on job search engines. If somebody calls you about a job, offering to give you a ride from your home to the company, that is a military recruiter. Don't be afraid to file a complaint against a cop, even if it really was your fault.
