Shooting Statistics

A PHP based site for helping break down some basic school shooting statistics, especially in relation to transgender assailants. This was created as a means to help combat propaganda blaming transgender people for the majority of school shootings.

Requirements

• PHP 8.0+
• MySQL 5.7+ or MariaDB 10.3+
• Web server (Apache/Nginx) or php -S localhost:8000 for local dev

Setup

1. Database

-- Run schema.sql in MySQL:
mysql -u root -p < schema.sql

2. Configuration

Upon first install, please load ./admin/login.php and follow the instructions to set up the database connection info and to set the admin password.

3. Web Server

Apache — ensure mod_rewrite is on (no .htaccess needed as-is).

NGINX — point root to the project directory.

Local dev:

cd school-shooting-stats
php -S localhost:8000

Importing Your Spreadsheet

1. Open your spreadsheet in Excel or Google Sheets
2. File → Save As / Download → CSV (comma-separated)
3. Go to yoursite.com/admin/import.php
4. Upload the CSV

The importer auto-detects column names (case-insensitive). Accepted aliases per field:

Field	Accepted names
Date	date, incident_date, event_date
Location	location, school, school_name
Deaths	deaths, killed, fatalities
Injuries	injuries, injured, wounded
Trans assailant?	trans, had_trans, transgender
# trans assailants	trans_count, num_trans, trans_assailant_count
Genders	assailant_genders, genders, gender
Total assailants	total_assailants, assailants
Source	source, source_url, url

See import/sample_template.csv for a working example.

Admin Panel

From the admin panel you can:

• Add individual incidents manually
• Edit or delete any record
• Import CSV files (bulk)
• View an import log

Statistical Methodology

The Analysis page computes:

• Trans assailants as % of all assailants — direct calculation from data
• Expected trans assailants — total_assailants × 0.006 (Williams Institute 2022 estimate: ~0.6% of U.S. adults identify as transgender)
• Ratio to expected — actual ÷ expected (1.0 = exactly proportional)

Population figure source: Williams Institute, UCLA School of Law (2022)

To update the population percentage, edit TRANS_POPULATION_PCT in includes/config.php.
