Honestly reading this it sounds more like a Resources management issue and not an equipment issue. As Sanctaphrax mentioned most of those items are publicly available assuming one has the funds to purchase them.
Not that this is an advertisement, but specialty equipment websites like
galls.com have police/fire/ems equipment, many pieces of which would be of interest to characters. A paramedic (ALS) level medical kit, complete with everything but the drugs and oxygen (it will have the O
2 tank) can be purchased for around $500. That puts such a kit at an Average (+1) Resource roll. For those characters with Good (+3) Resources, they wouldn't even need to make a roll, they could just declare that had it, assuming the situation was reasonable.
An example of an unreasonable situation would be for a player to declare their character has such an ALS kit immediately after another character gets hit (suffers a Consequence) during a firefight, as the party is escaping after having been captured. However, if the party hadn't been captured and was instead attacking a facility, such a declaration from a player would IMO be perfectly fine.
Now looking online, the US Cavalry site has Cavalry sabers for sale for around $100, a wooden Louisville Slugger baseball bat can also be purchased for about the same price. Both items would be considered melee Weapon: 2 items. Both can be easily purchased legally. However, neither item is very easy to hide, and characters would likely have some explaining to do if they came across a police officer with them, and it would not be unreasonable for a member of the public to call the police and report, "there's a man walking down the street wearing some kind of hooded cape carrying a fr*gg*ng sword!"
As a GM, I feel free to use normal responses to foil player's actions and ambitions. For example, when I ran the Sleepy Hollow game, a player thought it would be brilliant for his character to try and shoot out the tires of a van used by the bad guys, in downtown New Haven, CT at 5pm. The player was quite surprised and a bit dismayed when suddenly large numbers of heavily armed police started to show up, looking for the reported shooter. There is also the option later on for the forensic evidence to be used to tie his character's gun to the van shooting.
The other thing which I do, is I use a variant of the Bulldogs! rules for Resources. Basically I take Resources and make it an ability which every character has, but is no longer tied to the character's skill points. This makes it much more difficult for a player to raise it, so that players can't have their characters solve problems by drowning them with money. Let's face it, a Chest Deep campaign would allow a character to have Resources of Superb (+5) which means that items with a value of Good (+3) or $5,000 without even rolling.
