as8675/Crime-Atlas ? reverse-engineered prompt

Build me a web app that lets people explore Los Angeles crime data on a map.

I want users to be able to search and filter crime records, click around the map, and see details like the date, time, crime type, location, victim info, and status. The app should handle a large dataset smoothly and make it easy to spot patterns by area and crime category.

Also add a way to pull in Google Street View images for a crime location and save them so we do not keep fetching the same image again. If an image already exists, reuse it, otherwise fetch a new one and store it. Use MongoDB for the crime data and image storage, and make sure the backend has an API for getting crime records and fetching the scene image.

If you need current setup details or docs, look them up online and then wire everything together cleanly.
