The ugly part first: a post of you smiling does not equal "not injured"

That's the game the insurance company plays.

You're a Carmel student athlete. You got hurt at a school event, maybe helping set up a fundraiser, team booth, banner wall, or temporary structure near the field house. Somebody handed over a nail gun. The safety mechanism was bad. It fired when it shouldn't have.

Now the carrier has screenshots of you at practice, at a team dinner, or posting old highlight clips, and they're trying to turn that into "see, he's fine" or "he was messing around."

That argument is common. It's also lazy.

A photo proves almost nothing by itself. It doesn't show pain later that night. It doesn't show a hand injury hidden by the angle. It doesn't show you were trying to keep up appearances at Carmel High or pretending things were normal because you're 17 and didn't realize a claim would turn into a credibility fight.

Who can be liable here in Indiana

This usually isn't just one target.

If a defective safety tip or contact trip on the nail gun let it discharge unexpectedly, the manufacturer or another company in the chain may be on the hook under Indiana product liability law. If the tool was poorly maintained, altered, or kept in service after obvious problems, that opens up another lane against whoever supplied or controlled it.

Then there's the school side.

If school staff, coaches, or event supervisors let students use a dangerous power tool during a school event without proper oversight, that's a separate negligence question. Same if the school knew the equipment was sketchy and kept using it anyway. In Hamilton County, that fight usually turns on who knew what, when they knew it, and whether any adult actually supervised the setup.

And if an outside vendor, booster group, or contractor brought the nail gun onto the site, they may be part of it too.

This is where Indiana comparative fault matters

Indiana uses modified comparative fault.

That means money can be reduced by your share of blame. If you are more than 50% at fault, you're out.

So if a jury says your damages are $100,000 but you were 20% at fault, you'd recover $80,000. If they say you were 51% at fault, you recover nothing.

That's why the other side pushes so hard on student behavior.

They want to say you ignored instructions, horseplayed, grabbed the tool without permission, disabled the safety, or kept using it after noticing something was wrong. With a student athlete, they may add that you were "showing off" in front of teammates. It's a nasty argument, but expect it.

What the school or insurer will say was your fault

In a Carmel school-event case, the blame script is pretty predictable:

• you weren't supposed to use the nail gun
• you handled it carelessly or pointed it wrong
• you knew the safety was acting up and used it anyway
• your injury isn't that serious because you posted after the event

That last one is the social media trap.

A post from a baseball game at Murray Stadium, a weight-room selfie, or a clip from before the injury can get stripped of context and waved around like a smoking gun. If the timestamp is unclear, if it's reposted old footage, or if you were there but not actually participating, that matters. A lot.

For a high school athlete, the medical record often beats the post

If you ended up at an ER in Carmel, then got referred on, or were taken downtown to IU Health Methodist in Indianapolis because the injury was serious, those records matter more than your Snapchat story.

The first chart usually tells the real story: puncture wound, tendon damage, nerve symptoms, swelling, loss of grip strength, restrictions, pain with motion. If the nail gun defect is mentioned early, that helps. If the record says the tool misfired or discharged despite the safety contact, that's important.

Same with follow-up care.

Athletes get hammered by this because they try to return early. They tape it up. They show up for the team. Then the insurer says, "Look, he was active." No kidding. Teenagers do dumb, stubborn things. That doesn't erase an injury.

The fight is usually about context, not just fault

Carmel schools and families are used to organized events, booster operations, and lots of students helping with setup. That normal-looking environment can hide bad decisions. A polished campus in Hamilton County does not mean safe supervision.

Here's what most people don't realize: even if you touched the tool, that doesn't automatically make it "your fault." A defective nail gun is still defective. An adult letting students use it at a school event is still a problem. Missing warnings, poor maintenance, and no supervision still matter.

The social media issue works the same way.

A smiling post is not a medical opinion.

A short video is not proof of full strength.

An old sports clip is not evidence that a nail-gun wound, hand damage, or nerve injury magically vanished.

What matters is whether the post is actually from after the injury, what it really shows, and whether it lines up with the medical timeline. Insurance adjusters love screenshots because screenshots are cheap. Real evidence is harder for them.
