The reality is it's always cops being huge fucking pussies who can't handle even a small amount of adversity. So if they even think they came in contact with it, they're going to absolutely lose their shit, make a huge deal out of it, and attempt to get some sweet, sweet paid leave.
You can't trust cops, they're making shit up, because we allow them to. We know they're not actually scared of it, they're busy importing it to sell it.
Cops talking about Fentanyl are like Stanley Goodspeed in The Rock talking about "VX Gas."
Your muscles freeze, you can't breathe, you spasm so hard you break your own back and spit your guts out. But that's after your skin melts off.
VX nerve agent isn't a gas, and it won't melt your skin off or make you spit your guts out or break your back, although the rest is accurate. You'll spasm and suffocate.
When dealing with people in contact with fentanyl. Cops are a lot more standoffish and take things at a distance. This is mostly because it is very easy to overdose on fentanyl if ingested. While not as easily as media and superstition may have you believe, any exposure to the drug can be dangerous.
