Scammed for hundreds

I recently got scammed by a woman in person. She said that her car was broken down and she left her wallet at home and was stranded for some time and needed to borrow a few hundred dollars to cover the repairs on her car and she needed to get the money fast before her car got towed. She even said that she would pay me back triple once her car was up and running again and that she would meet me somewhere at 6:30 in the morning the next day to pay me back. The opportunity of tripling my money sounded almost too good to be true so l literally asked her "how do I know you are not trying to scam me" and she's like "oh no l'm not trying to scam you." Then she starts saying all this religious stuff. After some thought I decided to help her only cause I wanted to triple my money and I figured it anything went wrong I could report her to the police and the bank would give me my money back. So I went to a nearby ATM to withdraw $200 in cash for her as she said she needed at first. She said she needed a bit more for tires but l ignored her as I gave her a lot of money already. Then we departed our own separate ways as she took the bus into the city where supposedly her car was. I woke up at 6am the next day and texted her only for her to be somewhere completely different from where she said she would meet me. She texted me saying "I never made it home last night. Remember when I said I needed a few dollars more registering tire." I texted her back "why don't we just take an uber to your house so that you can get your wallet and pay me back." The next thing I know she starts making up several excuses for why she can't Uber home, get her wallet and pay me back. First she said "what about the kids, I don't want to leave them behind" I responded "they can come with us, an Uber can hold 4 passengers." Only for her to say "I don't have much time left before my car gets towed." I then took the train to meet her in the city. She said she needed $200 more for her tires repairs so I withdrew the money from the ATM and gave it to her. Then we departed again and later that day she called and texted me asking me to cash app her a hundreds of dollars more and I finally realized something fishy was going on and told her I wasn't gonna give her more money until she pays me back. I filed a claim with the bank to dispute the transactions only for my claim to be denied. The banker explained to me that I should never go to the ATM with anyone as that person could have a weapon and force you to withdraw all the money from the ATM. I also talked to a police officer over the phone asking him if there's anything he can do. He said "not really, that's too bad for you. She's been in the area scamming people for a while, you shouldn't have given money to her in the first place." And he simply told me "you are probably not going to get your money back." I was devastated upon realizing there is nothing I can do to recover my $400. I'm like "WTF I literally asked her if this was a scam and she said "no, this is not a scam." Why did she lie to me. I suppose if she admitted to it being a scam it would have been too obvious and I wouldn't have fell for it. I mean what is she gonna say "Yes this is a scam so don't bother falling for it." Everyone was telling me that nobody needs cash if their car is broken down. That should've been basic common sense.
