The Python code to redact every capitalized word and number and any sensitive words related to say SWAT team is:

import re
narrative = "This is a police narrative. This birthday 8/9/2014 will get redacted. This social security number 553-55-5555 will get redacted. This medication Xanax will get redacted."
words = narrative.split()
replacement_words = []
words_to_remove = ['robot']
for word in words:
    if word[0].isupper():
        replacement_words.append('**R:capitalized**')
    elif re.findall('\d', word):
        replacement_words.append('**R:number**')
    elif word in words_to_remove:
        replacement_words.append('**R:restrictedword**')
    else:
        replacement_words.append(word)
print " ".join(replacement_words)

Output:
**R:capitalized** is a police narrative. **R:capitalized** birthday **R:number** will get redacted. **R:capitalized** social security number **R:number** will get redacted. **R:capitalized** medication **R:capitalized** will get redacted.
